Pathetic Service

I have called Vodacom about a month before my contract would come to an end. I was advised I needed to call in the month of April to cancel my contract. Called in April to cancel, a week later I called again contract still has not been cancelled. Call the end of April, it was only then that my contract was cancelled. I was then advised I would be billed for May, but a query was logged for a refund of May. To this day nothing has been done. I am sent from pillar to post. Your service is pathetic and the way you deal with clients is mind boggling.
