Vodacom Ripoff continues

I must once again say that vodacom is a ripoff. I have logged three complaints to vodacom and eventually got a reply a week later only to be told by the person assisting me that he is not sure how he will be able to help me, so he will go and find out what could be done and get back to me. Hence another 4 four days have passed and still no reply. I feel that when a person pays Vodacom for a service as a example I pay them R 200 for air time and get R 28 then it is a ripoff. Vodacom gets R 2800 every month from me which they do not seem to complain about? Maybe the Ombudsman is a good idea? For me to terminate my contract will cost me a few thousand rand which for me as a pensioner is a bit much so they just do as they want.
