My XXXX year old daughter is receiving non-stop calls on her cell phone from " Cooper Hoffman & Klein Associates '' attempting to collect a debt from someone named " XXXX XXXX ''. We block the calls but they keep calling from other phone numbers. I called on XXXX/XXXX/15 and spoke to XXXX - I explained the situation and he hung up on me. They reference Case # XXXX and have called from these numbers : ( XXXX ) XXXX ; ( XXXX ) XXXX and ( XXXX ) XXXX. The voicemails threaten legal action and someone will show up at our house.
