Caller advised it was a courtesy call from T-mobile - tried to get me to verify account holder and account information. I did not provide it. Caller did not argue, but immediately attempted contact on other phones on account. This number is NOT a T-mobile customer service number. Beware
They have called multiple times and never leave a message. I called them back from another phone and when they answer they just say "Hello". I asked for the name of their company and she said that she could tell me the company name once I provided my name. Really?!?! Very rude and sketchy.
