Bad Customer service, unhelpful staff

This is not the first bad experience I had with telkom I contacted telkom several times with regards to my contact with telkomhow many occasions that the agents had assisted wasn't very helpful as they couldn't resolve a query at him on many occasions I have tried to cancel my contract there within send me the documentation to fill in which you don't have to send back to them in order for them to add it to the system to indicate that you have now made full payments and that the account will now be closed.documentation has been sent and yet the account has not been closed leaving me with an open account accumulating arrears. When trying to contact them via live chat the consultants only chat for two sentences and you have to wait every 30 minutes,pure utter bad customer service.
