FAILURE TO RESOLVE MY ISSUE

I had since settled my account with FINCHOICE MOBIMONEY and requested that the account be closed. Some few months ago, I received my monthly credit report and there was a balance appearing on my report. I called in to enquire about the said balance on the account and got hold of the consultant who told me that I had a balance on my account which had also accumulated areas. I then requested a settlement AGAIN and immediately made the payment and further sent through the proof of payment. It's been over 3 months now and I see the balance with areas still reflects. Can someone from FINCHOICE MOBIMONEY PLEASE explain to me how does your system work. I cannot be calling about the same thing OVER AND OVER AGAIN!!! It's really frustrating for someone who wants to keep their record clean yet you find CO's such as FINCHOICE damaging our reputations. I demand to know why hasn't my issue resolved!!! I have all the communication via email saved for reference.
