Unable to cancel a contract

<p>I have being trying to cancel a contract with Vodacom, to no avail. The customer care line just puts me on hold. I have been trying to phone for the past week and get put on hold. Everytime I am told that I will definitely be assisted. Guess what I am still on the line waiting for someone to assist me. This is really annoying and not the standard of services I would expect from a company like Vodacom. </p> <p>How are you supposed to cancel a contract you are not using if the number ********** does not even work. </p>
