These people claimed that they're from tmobile but they are not. They are scammers, they are trying to get your personal informations.
He told me that we need to settle of my outstanding bill. I told who the hell are you?? I'm current with my bill. I called tmobile just to confirmed if I'm behind on my payment, they said no. They advised to block that number on your phone.
Me too - just left T-Mobile and took my number with me. I hate T-Mobile - they were TERRIBLE. I wouldn't be surprised if it IS them. Anyone answer when this number called? Was there anyone there?
