I was given incorrect information on my contract!

I signed up for a new top-up contract last month using the Cell C telesales call centre. I was told by the consultant that my contract type (a top-up contract) could be used for international roaming. I queried this because my previous top-up contract did not allow international roaming. But I was assured that I would be able to roam on this contract. I HAVE to have roaming as I travel a lot for work.<br> <br> Now I find out from Cell C that I cannot do international roaming when I called to enable roaming for my trip overseas tomorrow. I was given the wrong information and so selected the wrong contract! <br> <br> Cell C must now take responsibility and either refund me or sort me out with a new contract that can do roaming and at no additional cost to me. They gave me the wrong information. Now they must bear the cost.
