This number, as well as 412-888-0296, 0266, 0325, 0265, 0326 - they call at LEAST 10 times a day, relentless. Anyone have any idea who it is? Is it spoofed?

They are a collection agency called ERC.  Website:  https://www.erccollections.com/  They contact my in-laws about 5 times a day.  Cannot get anyone on the phone.  They will not remove my in-laws number from their data base.  

Call starts with a recorded statement that the call is being recorded. Human identifies herself as Kimberly Wilson. Asks for another person, not correct one for the number. No other information available about caller, hung up. Assuming debt collector//skip tracer using spoofed phone numbers.

Calls and never identifies who is calling, never leaves a message. Doubtless a scam.

Calls trying to find out if you have student loans. There is another ERC but that one is affiliated with the government. Also call saying they are looking for someone but won't identify themselves. They call constantly. Regardless if you block or report them. They use different extentions of numbers when calling you.
