Receive several call a day from early morning to about 9 p.m. usually just 2 rings and they do not leave a message. Also get many calls from RPM often just 1-2 minutes apart, weekends and evenings. When tried to block RPM number 877-233-8521 was told it was an incorrect number.
I have no idea who is calling from this number. They call several times a day, nothing shows up on caller id, and they never leave a message. I'm so tired of this, why do we even have a "do not call" registry?
