My husband and I are being called repeatedly by XXXX different debt collection agencies. XXXX collector says they are trying to contact a person with a different last name, and if we are not that person, just hang up. We have hung up repeatedly, but they just keep calling and calling, often more than once a day. I tried calling them to complain, but their XXXX number was busy. 
The second agency says it is ERC, a debt collection agency in XXXX FL, but we suspect it is someone else pretending to be them, as they are using a different number. They give us a case number and tell us to call back, but we have not done so, because we have an excellent credit score, and KNOW we do not have any debts that would be in collection. Besides, we have friends and neighbors who have been harassed by people like them for months, claiming that debts are owed when they are NOT owed.
