Fraudulent activity by a TMobile employee switching my SIM # to a new device to steal funds

I just wanted to deal with T-Mobile and they already gave me hard time before I start! a guy his name John , who I couldn’t understand his accent! got all of my information including social security, we talked 2 days before trying to activate prepaid esim on Apple Watch but it didn’t work out then he advised me to switch to postpaid and to create Apple Watch account for me and pay monthly $20 I accepted that, then he started to ask about my information and when we got to the social security number I told him I don’t feel comfortable to do so online, let me think about it and you can call me in 2 days, he called today and I gave him all the information and the credit card information then for some reason we got disconnected, he never called back And I tried 10 times so far with customer service to know what happened or at least to transfer me to any supervisor but it likes talking in well, you hear yourself and the other side doesn’t understand you and you don’t understand him, I believe the customer service is not on USA it’s in India and communication sometimes goes to dead end, ending up for the customer service representative to pretend that he is not online and them disconnect you, it’s very frustrating! all what they know is to keep transferring you from one to one and no one can help 

really sad !!!!!
