Why wont you close my account? Close my account.

i have requested a settlement amount. I asked the procedure on how to close my account. I paid the amount to settle my account I send a letter and id via email and fax as per advised received from the call centre. I emailed it to [Email Removed] and fax:***. This i did in December 2013. I have been sending it over and over again so there are no excuses that they did not receive it. I am sitting here two months down the line still begging for my account to be closed. I dont know what else to do so this is my last resort. I have received the worst customer service from the call centre and RCS in general some of the the things im not going to go into detail. I dont have the time nor energy for it. All i want is my account to be closed so can you please do that.<br> <br> Thanks<br> Sharon
