14 dyas of run around and no response from executive team

What a nightmare.  I tried becoming a T-Mobile customer through their phone, and it has to be hands down one of if not the worst experience, and it's still ongoing. I attempted to trade in four phones for four new iPhone 15 pro over the phone.  First off, the original salesperson completely screwed up the order, only put in one IMEI number and left off the other three, and told me i didn't need them, she had a workaround.  She told me I would get $1000 per phone and there would be no charges for the phone.  My total monthly bill would be $160.00 because I am a disabled veteran and there is no phone payments cause the charge for the phone is the same as the rebate. Lie #1.  She then told me I would owe $287.35 for taxes for the phones and a $100.00 deposit for a total of $387.35. I questioned the deposit fee because I have over 800 credit scores, she told me I would receive the $100 back in 72 days (yes days).  I had her repeat the amount and accepted it just to get the call over with cause she was horrible.  Imagine my surprise when T-Mobile billed me $789.31.  Lie #2. I called arguing what i was told and then was explained it was taxes, $400 in deposits, and a $105 activation fee, even though their website and advertisements said no activation fee. I argued first i was told different amount and t mobile needed to honor that amount and then i argued why there was an activation fee even though i have screen shots  and every other advertisement sent out showing no activation fee.  I was told I would receive the $400.00 back once they receive my phones in 72 hours, then told they would reverse the $105 activation fee. Yeah they never reversed the activation fee. Onward to the next round of lies.  I received my iphone pros i ordered and noticed only one IMEI number on the return shipping label. I called again questioning what about the other three phones and how would i account for them. After some passing around and nobody having a clue the fake supervisor Mike told me to go to the store and they can fix everything. Another lie. I walked into my local store family in tow with all my phones and they pull up my account and tell me there is nothing the can do, there is only one IMEI and I have to call customer service back. So three hours on that phone that night again. and now another fake supervisor who keepstelling me she has to check with her supervisor says she has a work around to add my all my trade ins on the account and she is sending me a shipping label with all my IMEI listed on there.  Low and behold what do i get a shipping label with only the iphone 15 pros on it and nothing showing any documentation i was sending in my trade ins.  She then tells me that I would be charge 5 dollars a month for my phones, and also i would not receive my $400.00 deposit back for my phone and that it counts toward the purchase price of my phone.  But the $1000 rebate does not pay off a $1000 phone.  apparently I have to pay $100.00 extra per phone and $20.00 extra a month for a $1000.00 rebate for a $1000.000 phone so techincally tmobile is charging over $1200.00 for an advertised price of phone of $1000.  Again a little bait and switch.  The fake supervisor told me I would get back my deposit and still ahve to make payments on my phones.  Whne anyone can make a $1000 rebate on a $1000 phone turn into $1200, please let me know. Again I have no clue out of the 15 different people (Ferdinand, Leo, Jay, Marvi, Mariya, Jonry, Mike just to name a few) how nobody has a clue what to do.  Finally I had to resort to sending all the new i phone pros back to t mobile and now have been told 5-7 days to get my refund.  Oh and that whole I will text you or send you my personal guarantee, yeah never received one from any of your reps. Everyone apologizing and nobody fixing.
