Debt Settlement

I had a debt with Wonga, my account was handed over to Blake associates, I was given 50% off to settle the loan which I did. It has been about 3 weeks since I settled my loan and Blakes associates put in a request for the remaining amount to be taken off my profile however that has not been the case. I have been endlessly trying to reach out to Wonga but no avail when I get through to someone they ensure that it will be processed and account will be closed, they have been saying this for about 3 weeks, the money left in my account is incurring other charges which should not be there.

Wonga is still trying to debit my account of the remaining amount but they can see the request to have the account on their end. I just need this issue updated and account closed.
