T-Mobile Tmobile stole 345.81 USD from my checking account United States Nationwide

 T-mobile charged my checking account 345.81. USD. I am not an account holder nor have I ever done business with T-mobile. I contacted the general customer service line and they transferred me to the customer service department that handles this type of inquiry. They verified through my social security number that I did not have an account. I requested that they investigate the transaction in order to determine how they were able to access my checking account via an ACH. They refused stating there wasn't any way possible for them to trace an ACH from my checking account. I find this highly questionable. I stated that they could research the transaction since it was a financial transaction which is by law required to be tracked. I offered to give them my checking account number, the phone number to my bank etc. They refused to take any action citing it was my banks problem. I have contact the FBI and alerted them to the scam. I have seen numerous complaints regarding tmobile online - apparently this is something that has occurred thousands of times since 2009 and continues today in 2014. Why doesn't somebody shut them down?
