Retrieval-Masters Creditors Bureau, Inc. Debt Collection Complaint

Retrieval-Masters Creditors Bureau, Inc. Debt collection department,

Cont'd attempts collect debt not owed Debt is not mine Nevada

There is a number that calls me - - - times a day ( - ) without leaving a voicemail as to what the matter is about. It started on Tues. - -, 2015 and has been non-stop since then. The call will last about half the length of time before my phone goes to voicemail so it 's impossible for me to answer. Then when I call back it is a phony English automated message. I have no idea what debt they are trying to collect. It 's starting to get really frustrating. I recently changed my address and received a bill in the mail for no-show from a doctor whom I never seen. I 'm wondering if that is from them?
