@Phil_Adelphus Even if that were the case, there's still no way to get surprise overages. Someone had to sign up and pay for something consciously. Either via the online account, or by responding to a text offer from the phone.
Or it's unrelated to the OP's account and someone stole their credit card and bought their own PM services. This is where screenshots of the account history would be helpful. At this point it's a guessing game. I'm confident there is a logic explanation though.
