Telkom - Worst Service Ever

Despite the constant lack of service and the multiple issues one face when working with Telkom. They have not updated my Transunion account since July, this is creating a problem when applying for credit as I spoke to the transunion consultants when inquiring as to why my applications constantly fail. I sent in a request for this to be updated on the 4th of December. Talking to a Brenton Oliver, he sent the email and CC'd me in to Credit Management Delisting as there is according to him and most I have asked no way of contacting them myself and sorting this issue out. Today when logging onto Transunion, still nothing. And of course no one can assist me when calling Telkom because why would they with their level of customer service. Because of all this and believe me more struggles I have canceled my account. Which has not been canceled even now after the 21 day period that I was told to wait, and waited. Today my account is still active. Is anyone actually capable of assisting a person at Telkom and showing results?
