For four ( 4 ) years my family and I have been receiving harassing and threatening phone calls from a debt collector who has gone by the name of " XXXX ' or " Concord Resolutions ''. If we speak to them they refuse to give us info. on who they are, where they are, what number they are calling from, etc. ( they call from hidden numbers ) what the debt is, etc. All they will say is they are looking for my Sister, concerning a pay day loan debt. They threaten legal action against us if we do not cooperate, tell us a deputy is on his way to pick us up, etc. They are calling all of my immediate family and now are starting to call in laws! They have left messages to call # XXXX and speak to a XXXX XXXX but a woman has called also, refusing to identify herself. They call all day long on all of our numbers. And it 's not limited to the adults. They are calling the teenagers / children 's cell phone numbers as well. We have no idea how they are getting these phone numbers. Once you speak to them and start asking questions or advise them to stop they seem to " ramp '' up the harassment. Like it is a game to them.
