THE WORST SERVICE EVER

On the 28th of January I went to the above store to 1. Cancel the existing line and 2. Do the change of ownership on my new line as I had just purchased a new home . Number 2 was done almost immediately but number I am still being billed for the line was supposed to be cancelled at the end of February. After a myriad of clalls and promises made by Telkom to date nothing but nothing has been DONE . i am at wits end as i have no right of recourse as they did not give me a copy of the cancellation form and when i asked them for it they sid they had sent it through to the relevant department . What to do ? I no longer want to be associated with Telkom in any shape or form worst service I have ever had form a service provider . Saturday i will visit the store one more time TO CANCEL EVERYTHING WITH THEM !
