Called my Sprint mobile claiming they are calling on behalf of T-Mobile for someone other then me... I've had this number for 3 years and never had T-Mobile nor am I the person they were calling for.

I called back mess with them a few times, the "please hold, it's very important we speak with you" message didn't sound legit and they have the same 5 people answering the phone. Asked for a supervisor but got hung up on everytime.
