VODACOM IS ***********!!! USELESS

A contract of mine that was supposed to expire and not upgraded, was upgraded on my account without my consent or approval. After 100 of times to my nearest Vodacom store I decided to go the ***** department way, still after several mails and calls (15 months) no feedback or problem solved. Vodacom staff cant explain or prove what is on system its upgraded THATS IT. i escalated the case to ICASA which is still in process ..... In the meanwhile (last 3 months) as I'm a pensioner drawing a pension only, NOTE that the contract was upgraded from a small amount to a contract over R800 a month, I stopped paying that contract as I'm battling the last 17 months with Vodacom to resolve this and could not pay that anymore, I cant even buy proper food or survive as I need to pay this contract. My second contract that I do have still that expires soon was NOW disconnected NOTE is paid every month manually at Vodacom outlet since I stopped 3 months ago to pay the R800 for a contract that I did not approve off or getting resolved. IM SICK OF VODACOM!!! There staff is *********** and there system is POOR. How can this not been resolved?? How could this happen in the first place if I did not UPGRADE??? I will recommend NO ONE to go the VODACOM way.
