If you listed the account in the BK, and they didn't respond, they would not be included in the BK plan or repayment, but could no longer legally collect from you.
If you listed the account in the BK, and they did respond, they would be included in the BK plan and when it was discharged, they could no longer legally collect additional funds from you.
In either case, a letter reminding them of that fact should be more than enough - no copies of the discharge would ordinarily be needed.
However, it appears that you did not list the account in the BK. In that case, I believe they can still collect from you - including late fees and charges.
It sounds like your recourse is with the account rep from the collection agency (yeah - I know....nothing in writing - right?)
At this point, I would touch base with your BK attorney, rather than soliciting legal advice from, well - from us. If it were my BK attorney, I can promise you he would not be happy with me if I brought this situation to him.
We were warned with red flashing lights and sirens to include every last thing in our BK. Everything. Every little thing. Failure to do so can result in an immediate dismissal if the trustee is notified; or in your case, some loose ends that could have been handled in the BK but were not.
I hope you're able to work things out with this company - I'm sure you've been working very hard to rebuilld your credit. Best wishes as you move forward on this! I'll keep my fingers crossed for you.
