I was getting calls from 269-477-2153 for a couple of weeks. They never left voice mail. I never answered but finally started watching for and rejecting the call. That number stopped but then right away I started to get calls from 425-437-0651. Last night I accidently answered. They asked for someone else. I said it was a wrong number and do not call again. We'll see. Are these two numbers the same source? The area code 269 is Kalamazoo, Michigan and 425 is out of King, Washington. But you never really know - they can re-route numbers and/or may have offices in both areas.
I think this is where the calls are coming from: their website gives you lots of info about this company.
http://www.receivablesperformance.com/ They use other numbers too, such as 269-477-2153.
I researched another number used by RPM. It seems they buy debts written off and are absoutely dreadful in their tactics. These clowns started calling a little over a month ag, Different numbers, no voice mail, no nothing. But what I read was if the company you are having a dispute with has written off the debt, you are under no obligation to pay. RPM has probably spent more money trying to collect than the debt was originally worth.
