I AM BEGGING FOR HELP - NOW FOR THE 3rd TIME

What does I need to do, PLEASE, to close my account? I have sent numerous emails, make many calls AND now posting for the 3rd time on HelloPeter and yet NOTHING gets done. The last 2 times I posted on HelloPeter I received responses that it would be attended to immediately yet nothing has been done. I am really getting fed up as I have AGAIN received an account nearly 1 year since I first emailed Telkom to close my account. Surely this is not difficult. I can assure you that if this issue affects my credit I will pursue this. Please. I want this account closed by close of business within 7 days from today. Thank you.
