RCS is not closing my account!

On the 10th April 2015 I settled my account and emailed [Email Removed] with the proof of payment and requesting them to close my account. the call center told me they have my email and the process would take 30days. I followed up two months later to find out my account is still not closed. Same process app****! it is now September and when I called to make sure it is closed as I am busy with a home loan and this account will effect my lending ability. I am told they have no email (even though this was confimed as received by the call center a few months ago) and I am now to mail them AGAIN!! requesting my account to be closed and wait another 30 days! I DO NOT HAVE 30 MORE DAYS TO WAIT FOR RCS TO NOT DO THEIR JOB. I WANT THIS ACCOUNT CLOSED TODAY!! MY HOME LOAN IS ALREADY IN PROCESS.
