mweb uncapped is not uncapped!!

We signed up for the UNCAPPED adsl for R230 around the 20 January. Our internet was slow from day one and we eventually got throttled. We run an internet based business and I had made it clear that we had wanted uncapped. Well now after being throttled and losing out on business I called the call centre and said that we would like to cancel and they should not debit us for March as we are unhappy with the horrible service. I was told that we need to give one months calendar notice and that the March debit will have to go through. Unhappy and very disappointed with this service from mweb. Don't sell uncapped and then restrict your customers. That is lying to us!! We paid for uncapped and since you cannot provide us with it at least allow us to cancel!<br>
