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.
I recently dumped t-mobile as my cell phone service provider and started getting calls from 201-297-4498. I contacted T-Mobile regarding these calls and was told that this is not their phone number. It is obvious that whoever is calling has obtained my number illegally! WARNING!! Do not answer the phone when they call -- if you do, be careful to not provide them with any personal information! The calls from this number is obviously a SCAM caller!!
