Do you feel scammed by tmobile business?

Ok I’m going to be as detailed as possible so I can see if anyone out there is having the same issue or can potentially help me resolve mine. 

On March 3rd 2024 I made a decision to open a T-Mobile business account for my non-profit organization. I'm a Gold Star Child which means I've lost a parent to the military & I mention that because it's the reason I even was interested in doing business with T-Mobile. Many Gold Star organizations sing the companies praises & they also offer us a discount which is something I appreciate even after my less than ideal experience. 

It was on the 4th that I went into a physical location in Iowa. The staff there & myself sat there for 3 hours sorting out the details. But at the very end their system in store malfunctioned & they were unable to take any payments. They told me to come in the day after next. 

On the 6th I went in again & again we sat for a few hours. Only to be hit again with a roadblock that required someone with more authority to help get approval. After listening to the staff complain they were scared to call their supervisor I said I'd talk to him if they weren't so inclined. When he got on the line I explained my frustrations & he asked me for patience. Told me he'd be there the following day & he could help me then. 

7th came, he wasn't there. Although I had been hesitant to do something over the phone I had just about had it with the store experience so I asked for the number to the business department & tried there. 

All went well over the phone & via email so on the 8th I paid a $700 deposit. Then went ahead & cancelled my existing cell service with another company. As I was assured by the business specialist that my new phones would be shipped overnight. 

Delays with shipping postponed the arrival of the new devices until the 11th but I patiently waited & made do without a phone for a few days. Working around it the best I could. 
On the 11th I eagerly awaited as the tracker had the phones in my town. It was very exciting! Until 2 hours before they were set to be delivered I got a message saying T-Mobile had cancelled the delivery & requested a return. When I contacted my business specialist they were shocked & told me it was certainly a mistake. 
It wasn't. T-Mobile wanted more documents for verification which is fine with me, I just wish they had asked prior to them reversing the delivery. So I emailed a very specific email they gave me with what they asked for. Customer support said on a call that they would have an answer for me that evening. They didn't. 

By the 13th I was done with this goose chase. No one had contacted me by phone or email & no one had any answers for me so I gave up. Requested a refund & was told it would be back in my account within 2 weeks. 
That would have been a dream! After 2 weeks I checked in, nothing. After a month, nothing. Then almost 2 months later I got a bill in the mail saying I owed T-Mobile money for the account they cancelled & I had already been told I was being issued a refund for! So I called furious & demanded to know when I would get my money back. 

Instead of giving me a direct time frame or date the customer service representative told me the process. She said the phones had to be returned by the delivery company then inspected by their people. After which point they would schedule me for a refund roughly 6 weeks after that. When I explained how I never even touched the phones & how there would be nothing to inspect because they never crossed my path so any damage would have been on the delivery company. I was told there was nothing anyone could do. As upsetting & unfair as that was I was even willing to roll with that until… 

A second bill with later fees now tacked on showed up. Additionally the phone still seems to be stuck in shipping limbo. T-Mobile says the might have it but they're not sure, the delivery company says it's still being returned & I'm still stuck without my money! At this point it's not even just the original $700 loss that I've had to carry. I've got the fees for cutting my old plan, fees for reinstating it, the travel cost, bank fees, time lost & stress gained all because I thought T-Mobile was good people. 

I feel like I got played. Please help.
