Perhaps ask iQor, Inc formerly CBCL - Canadian Bonded Credit Limited - Now Iqor Collection Agency to validate when the last payment was made, and have them also supply documentation to validate that data.
Once that's in hand, then determine what you want to do. Until that's in your hand, it'd probably be wise to hold off on any offer. From what I've been led to understand by reading other posts on this site, if iQor, Inc formerly CBCL - Canadian Bonded Credit Limited - Now Iqor Collection Agency cannot produce the documentation which validates their position, you may be able to have Equifax and TransUnion adjust your credit report accordingly.
Good Luck!
