Terms and conditions not explained!

<p>I am absolutely perturbed with the way vodacom works. In February we upgraded 1 of our business contracts to a 75min 200mgb line for R399 with an iphone 6. In April I asked vodacom workshop if they could give me more minutes as I wanted to try it out for a month or 2 to see if it works for me. They did not tell me that I wont be allowed to downgrade later. They also told me it was R749 per month and did not say that a further R170 handset charge was not included in it. After 1 month when my bill came they had charged me R809 +R170 plus another R100 for bundles. When I asked them to downgrade me to the original contract which we signed for they say I have to pay R2800. When I said they didnt tell me this previously they say they cant do anything about it. The number is ********** 786 and I would like vodacom to honour its deal. This is unfair and ****************!</p>
