Debt collector ERC claiming to collect a debt that we DO NOT owe. Will not provide any other information other than to say the debt is from XXXX and that the amount owed is {$66.00}. Will not provide any proof. Continues to call ... We are still customers of XXXX and have n't received any information from them. XXXX is trying get us back as a customer. Why would they want us back if we still owe them money? The Email address they used to contact us is over 10 years old. I think they are fake and we paid a XXXX $ debt to a collection agency 2 years ago, we may have been scammed then.
