Bad Customer Service

I am dissapointed in the way Mr Price non response to my submission of closing my Sheet Street account has been neglected, i e mailed the accounts department twice during the previous month to inform to close my account completely and send me a final statement with balance so i can settle the account, and also after closure update It on all the ITC. Uup until now i have not received any response from the offices, my son tried to call yesterday to try and find out what the situation is because my english is not as good as it should be with slurred speech and lack of communicating, he was abruptly told that he can not communicate on my behalf and the call was dropped. I am now fedup, i want this account closed, and a final balance to be submitted to me, so i can pay the balance owing, and have my details updated on the credit beauro's as CLOSED UP TO DATE. Why is this becomming such a difficult task for Sheet Street to do this ??
