Non existing accounts department

This is my second complaint report on Hello Peter, but my Telkom account has still not been sorted out. It has now been three months of continuously trying to get hold of someone that can help me sort out my Telkom bill. They never answer the phones and when someone answers the phone, it is the reception lady. She then puts me through to the accounts department where I wait for another 45 minutes until I finally get through to her again. It is very frustrating having to work with Telkom. They are very unprofessional and simply don't care. They charge me every month for data that I don't receive and I cannot get through to them to find out why they did not cancel my account after I told them to. I received a call from someone from their social networking complaints department about my previous Hello Peter complaint report and she apologize for the inconvenience, but that is where it all ended. She said someone will contact me shortly, but it is now two weeks later and I have still not heard from them yet. Not even she does her work properly. How do I sort out my Telkom account?
