They call me numerous times a day with threatening voicemails about taking me to court and me having to pay court costs, but they have n't sent anything in writing stating why I owe them and for what, how much, etc. They are calling my previous place of business, my home ( which I never give out ) and my cell phone- I get at least 5 calls a day. Please help- if they would mail me validation of debt I would be more inclined to call them, but they have not. All they do is leave threatening voicemails. 

I do n't know who they are ( besides being a debt collector ) and why I owe them. They never stated what account they 're collecting on, and further more, when they call my old place of business they 're leaving a voicemail on someone else 's voicemail- this information should be private. It clearly says someone else 's name when the voicemail comes on- so they should n't be leaving a message with them at all. I have n't worked there in months. It 's humiliating because my previous employer is contacting me again about this. I 've told them to ask them to stop calling, but they clearly ( Cooper-Hoffman ) are not complying as requested.
