Vodacom charging me for cancelled contract!!

On 5 February I requested a premature cancellation on one of my numbers. At the end on February (beginning of March) I saw on my statement that the phone had not been cancelled and that I am still paying subscription fees on the number.

I phoned VOdacom a few times and every time theysaid they were working on it. The number has apparently now been cancelled, but Vodacom still expects me to pay subscription fees for this month! They said they would deduct 25%. Why should I pay anything if it was not my mistake?

Vodacom is making money ouot of a cancelled contract. This is really pathetic service. There is not one word on compensation for the inconvenience and trouble they are putting me through.
