i got a weird call from this number it showed up as 'RECEIVABLESPERF' on my caller id. i answered it and the guy was extremely rude and unproffesional. he said he was from rpm and he would call back later

someone called my mother asking for me i no longer live there and i never gave anyone that number

Three people, who identified as Tony, Ray and Jacob, have been calling my elderly parents (who I have not lived with in 30 years) asking for me. They say they are from RPM - whatever that is?

ps from previous "Fed" message above
I also have never given out my parents phone number. I keep calling to find out what this is about, but the number is always busy.
