I get more then several calls a day, 12-15 times. I called back ONCE and they asked for someone else, or there was no answer.. The person has threaten me , i am not allowed to say! I If these harrasing demanding calls continue I will take this to court! Just so i can get peace and quiet.... The fact its a scam because the person on the line was VERBALLY ABUSIVE! and asked for money of a bill thats been payed for, in full a year ago! I have a 729 credit score and made all my payments from t moble company 7 years ago,SO WHAT THE DO THEY WANT! THEY HAVE MY RECORED! and its good SO WHY THESE CALLS? THIS IS REALLY A SCAM! I called T Moble and the company told me i am clear and have 0 BALANCE! But this number keeps repeating and this is the last straw!!!!!!!!!
