In writing request a copy of the contractual agreement.
You are going to look for a few things (These are Alberta regs, so check with your province for theirs):
1. Returns policy - is there one, what are the terms? How did you send it back? Proof, receipt. If your not entitled to a return then tell them in writing you want it back or simular.
2. Third party/collections provision - did you authorize them to send your information to a third party or collect against you?
3. Interest. Now this is the big one.
They cannot collect for interest unless you agreed to it. Collection agencies are big on trying to collect interest not entitled too, because it makes their "settlement" offerings more attractive and it intimidates you to pay them first.
Get a hold of that agreement first and foremost and see exactly what it says. IN Canada there are no laws that say you have to talk to a collection agency and they will lie and manipulate to get you to pay. Don't talk to them until you get this contract.
Also get a copy of you TransUnion and Equifax credit report and see if its on both. If so it will be present for 6 years from the date it was assigned or last acitivity. This is important also. Don't agree to anything as you want that date to go by as quckly as possible.
Also if they offer you a settlement, don't take it, and if they offer you a different contract, don't take it until you talk to someone first. Remember its your credit!!
