Two years letter Telkom wont pay back my credit

I cancelled my internet with Telkom and paid the cancellation fee. However was OVERCHARGED by R950, it has been TWO YEARS and Telkom has not paid me my money. I go to Telkom once a month and no one knows whats going on, they cannot let me use the credit on something at the store and they still refuse to give me my money.

They are the worst thing to happen to South Africa since AIDS. The staff are *********** and do not do their jobs. I went to Telkom in Canal Walk (Cape Town) and request the credit, the agent argues with me and demands a bank statement. I provide the bank statement and assures me the money will be paid in a weeks time. Bare in mind thats what they all say. After a week I go to Telkom in Bayside mall and they tell me that the previous agent had not actioned anything.

Of course he hadn't actioned anything because its ****ing TELKOM!!!
