How to file complaint about billing issue

I got my issue sorted out by a wonderful rep via facebook messenger. Totally 180 degree kind of customer service experience than I had with team expert Marcus who was unethical by lied to me. Thank you sayaoran for your reply. 

For more context with my situation, I called and reachout to tmobile team expert via phone in past Sept 2022 to requested them to STOP charging me for $15 which i shouldnt be charged in first place. This is for voice and Im deaf and use data only. They assured me in past sept taht they will remove this feature which never happened so it was tmobile's error and they owed me all $15 they took from me. Its nothing with terms and service agreement. 

I'm so frustrated I have been having to call T-mobile every month because the overcharge me . Something needs to be done. 

NEW SERVICE. Order placed on 8/13. Promise of delivery 8/16. Order on hold and if I didn't call wouldn't have been processes on 8/16. 1 day shipping and promised by a supervisor for 8/19. Tracking number emailed saying 8/20 by 7pm. Contacted UPS @ 440 to 450pm. Was advised package was lost and still in Kentucky. 3 way call with UPS, Tmobile a myself. Tmobile Supervisor (From USA) advised to go to store. Will cancel order and I would get credit. Also called store @ 1230 Coporate Drive. They were great. Issue is that because the phones still showing in delivery process, I would have to put down a deposit. Was advised per Supervisor (USA) that they will be no additional charges. Store gets involved and speaks to Tmobile CC (Non USA) and all you hear is excuses. "Upon looking" "Upon this" "Seeing what we see". Yet spoke to numerous Supervisors (Non USA) and all say I have to wait 5 to 7 days. Not happening. UPS verified they have a case in since 430pm this afternoon. TMobile non USA says I have to wait until tomorrow to call UPS. Even after UPS verified they have a case in. Needless to say, I am going to the store. I will get my phones. I will continue to call and be a pain like the "Extended Warranty" people. 

I am having issues with home internet 

paid bill on 4/29 through Apple Pay however tmobile claims they have not received it charging me reconnect fees and monthly bill however my bank says tm has the $$$ and has provided me it's docs. I'm frustrated I Neva have a problem will Apple Pay or my bank and can't understand tm issue and reconnect charges when they got the $$$.

First of I still can't log on my tablet app till couple of hours ago n seen my bill outrageous not happy I started of my bill beginning of year 175 now my bill 260  n customer service is more frustrating than ever n people are rude I have to wait over 53 min to even get someone on the phone I wonder why and I was supposed to be on the price lock to what happened to that.not happy going to find other provider if they would of kept there promise of price lock I would be happy to pay but now they losing customers

After years of service with T-Mobile, I decided to get three devices and I was not happy with them. Everything was sent back within my 14-day buyer's remorse then because of the customer service I canceled my service as well and now I'm receiving a bill for $317. When I canceled all services I was not under a contract and my phone was paid for. I sent My old phone in. Never got it back. They have told me that it is in  investigation but they still keep sending me a bill which since investigation supposedly started the bill went up 40 dollars. When all services ended they were supposed to send me $95 for my old phone plus plus reimburse me $35 activation fee. Then told me that I would have to wait 30 days to call and request that and when I did they told me I owed $284 and now $317.p if somebody can help with this it would be great. Did you

There is a cap on the credit you can receive.  It's literally listed in the Terms of Service that you sign when you join T-Mobile. 

 

As mentioned in the DM you sent.  Reach out to T-Mobile on Facebook or Twitter through a direct message.  They start off at their 2 support.  They can escalate your complaint to the Executive Team at your request if you aren't happy with the resolution they offer.

I wonder if that's one of the reasons T-Mobile's executive team is grouchy at me.  When I call in for a status on an area that's been out for +6 months, and they fail to debug it, their offshore team offers credit.  I've told them that I'd rather have them fix the service.  T-Mobile executive response team has basically put a block on my calling 611 for support because their teams are giving credit too easily. 

I have never had a phone service that is so stressful, this is by far the worst company I have EVER went through, not to mention how 💩 the phone service is. We have 3 lines on our account and usually our payment is automatically taken out of my fiancés account but this time I paid it with my card so our lines would not get disconnected and so we wouldn't be charged $60 ($20 per line) for a reconnect fee. The payment submitted with a confirmation email being sent to my email, and they still disconnected our lines. This has happened at least 5 times in the past month and a half. Our phones at this point has been off more than on and we keep paying every time they say we owe. We called customer service and spoke to several agents as well as managers. One agent had me on hold and eas processing it to have our lines turned back on but we got disconnected and when I called back all they said they could do was apply a credit to my next payment which they tried making me pay before getting our lines turned back on. I did not pay this, because common since if ur willing to apply a credit then you r in the wrong.  But they sure wasn't willing to take off the $60 that got we got charged for our account getting disconnected even though we paid. As soon as we find another provider we will be switching. I have heard so many bad things about this phone service and should of listened but we put faith into this phone company and have not had a good  the whole time we have had our service. If you want to get screwed over then this is the company u want but I highly recommend you do not use their services. WORST EXPERIENCE I HAVE EVER WENT THEOUGH WITH A PHONE COMPANY!!!!!
