called late sunday afternoon is a company called rpm or receivables performaance management. Have had several lawsuits (check ripoff.com)... these guys are relentless and don't care about breaking the rules.
571-261-0038 is a debt collection company, Receivables Performance Management.
They're trying to collect on an old T-Mobile bill that has already been taken care of.
On 9 May, 2011, received call from person who asked for Gary. Told them they had the wrong number. I have had this phone number for a year. Recently I had the voice mail disconnected because I had so many calls from unknown phone numbers. Meanwhile I registered on the do not call list when I first got the phone from Verizon, and registered again a month ago. Normally calls show up as a missed call and I immediately delete them without looking at them, but this was one time the phone was on and I answered when it rang.
