Nimble is keeping me from getting on with my life after debt review.

I have been trying for over a month now to get a paid-up letter from Edgars/Nimble. I need the letter to send to Debtbusters to get a clearance certificate. According to Nimble and Edgars, I am not on their system therefor they can't issue me with a paid-up letter. I had an Edgars account registered at Debtbusters. What I later found out from the NRC is that, when Edgars was taken over by another company they lost some of their records. So now they are only shrugging their shoulders and refuse to give me a letter. According to the NCR they need to give me a letter stating that I don't have and account with them and don't owe them any money. I have asked them several times, without any luck. The amount of anxiety this is causing is debilitating. I have paid up all my debt but can't get a certificate because Edgars/Nimble lost my records.
