Worst Service Ever

I requested a closure and paid up letter of my account to be sent to me on 01 Oct and to date i still have not received anything. Spoke to a lady called Carol Nortje from your call centre and still no luck. Then logged a complaint and two days later still no feedback and the only thing your call centre consultants can say is "I will email someone". Why does it take you so long to simply close an account and issue a paid up letter?????? I have never dealt with such *********** people in my life.
