Wonga Loan under-debt review

Good day

I have been under debt review since 2017, I just recently found out that my Wonga loan accounts balance is still the same as when i joined Debt review even though HTN attorneys say it is paid off. I spoke to one of your consultants who advised i send proof of payments. I attached Hyphen proof of payments and emailed it to Customer care email address on the 27th august, till today i haven't received any response from them of whether the amounts are allocated and how much is left as this is the only account i am left with to get my clearance certificate.
