Someone in XXXX is using my social secuirty number. I sent a questioner to XXXX XXXX XXXX and they then sent it to a collection agency, they told me to report it to my local police department and send them the file number, which I did. That collection company has now sold it to another company and I answed in a letter to them what had transpiard and that they should not contact me again!! which they have. I call and tried to explain that they had bought a bad account he responed he would see me in court!! What do I do about this harrassement?
