Good bye Cell C

I phoned in yesterday to cancel my contract. Was fed up with the horrible service. But, stupid me, was persuaded to move to another package. Part of the package was 500Mb of data. So my pro-rata data runs out last night. Impossible, so I phone Cell C. Somehow I now only have 50Mb of data a month suddenly. Ask to speak to the supervisor who assisted me yesterday and he seems to have disappeared off the face of the earth. No record of him (afrikaans white guy). I ask to listen to the recording of the T's & C's and contract details he read out to me, am told to go to a store. Apparrently, they think nobody works. I ask them to listen to it themselves and load my correct data, am told they will send a request, will take time. So in the meantime I will have to BUY more data to be able to do my work. Was this the plan all along??? *****ing some more money from me??? I am buying more data now to work, I have to, and expect it to be removed from my bill once they correct their mistake. Then I will this time definitely cancel my contract. The almost hour I spent on the phone was great for my productivity as well.....
