T-mobile's Misguidance and Misinformation ( SCAM )

So, Weeks ago I had purchased a T-mobile Phone, They scammed me saying its Unlocked, However I managed to transfer the phone on my account and asked T-mobile customer service to unlock it for me and they checked into my account they said according to T-mobile Terms The account should be $100 paid or 365 days to be with them, so my account was already $60 all I had to do is to process with $40 or more So he made me refill my account with $50 and told he would unlock it for me and I will have it unlocked it within 72 hours.

However then I relied on T-mobile customer service I paid $50 more and refilled my account he told he processed with unlock request and would be unlocked within 72 hours, but it’s been over 3 weeks phone is still locked and now when i contact the T-mobile 611 again they are giving different information every time i contact them.

So My Concern , Question and Next step:

Is T-mobile so unstable to Handle customers with improper customer service just making people give them money in any possible way?

For this I could pay more but I feel played with both the Scammer and the T-mobile which has possibly too scammed me with making me pay with false information or this is how T-mobile works.

My next Month would be with Verizon at least they help their customer and no false information neither the forced payments scam!.
