I recieved constant calls from SW Credit Systems L.P. # XXXX about a XXXX XXXX for {$380.00} that was not mine. I call several times informing them it wasnt and I never lived in the XXXX area. They said someone must have gotten my Soc Sec number and they wanted me to pay it anyway. I refused and now I see they have placed my credit in collection and My score has dropped from XXXX to XXXX. I am sure this is an unreputable company after the many phone calls I made to them. Please let me know how to proceed in getting them to remove this black mark and completing this complaint. Thanks XXXX
