Cancel my contract!

So I requested on the 17th November that mine and my husbands contracts be cancelled, since we have no signal in our house, which is where we do our business from. Mine got cancelled yesterday, but not my husbands. Vodacom is not answering my messages and emails, and their cancellation department say they have no knowledge of a request to cancel his contract. Vodacom you leave me no option than to write this review, as I don’t know how else to get you to take the request seriously.
