CBV collection agency.  Called me this time last year too.. about a Rogers Mobility Bill that was put in their hands but they had no actual bill or records to verify there was actually a debt owed.  They put a smear on my credit rating. I called Equifax and had them investigate it and they weren't satisfied that this agency had a legitamite file on me and struck it off my credit report. Now they are trying to collect again. I have read that they often try to collect on debts that people have paid them off for as well.  They are shady.
