Complaint Review: West Bay Acquisitions

 I received a collection notice from this company for $32.83 for a purchase from BMG music services, which I have never used or heard of.  On top of that, The name they used on the "invoice" was neither my legal first name or the correct last name or address as of the past 4 years.  My biggest concern is on the back, it states, if I dont reply in the next 30 days, the debt will be accepted legal and true.  How can I dispute a claim, I should have never been able to receive and is not in my legal name for over 5 years, yet is just now going to collections... I'm scared to contact them, fearing they have technology that could further make me a targer for their fraud.
