I received a call from E.R.C. on my cell phone. They were trying to collect a debt from XXXX XXXX from XX/XX/XXXX. This account was paid in full. They had my name and mailing address, and even told me a balance due. I told them I would call back. 

Upon returning their call, they asked for my social, which I refused to give out over the phone. They then told me that they could not discuss my account without my social security number. I told them to stop calling me if they could not discuss my account without information that could be verified without personally identifiable information. I have never received a letter, reference number, or any further correspondence until today ( XX/XX/XXXX ). 

I have researched the company online, and there are numerous complaints regarding their questionable practices. 

The number from which they contacted me : XXXX ( XXXX XXXX XXXX, USA
