Debt collection — The Affiliated Group, Inc (OH)

Debt was paid. I closed an account with XXXX XXXX of Ohio on XXXX XXXX XXXX, when I sold a house. I disputed the final gas bill and on XXXX XXXX XXXX received a final bill for {$39.00} which I paid on XXXX XXXX XXXX.

I contacted that office and informed them that I had received and paid a final bill totaling {$39.00} and after speaking with a supervisor XXXX agreed the notice was in error. Today XXXX XXXX XXXX I received via XXXX mail, a notice from Affiliated Credit Services stating my previous account with XXXX XXXX was in collections and that I owed {$26.00} on the account.
