No response on e-mail and no answer at call centre

Good day,<br> <br> I was misleaded by a consultant in believing that they are going to upgrade my contract but instead they sent me a new contract.<br> <br> I have been trying endlessly to contact the customer care line *** without result.<br> <br> I want to cancel this contract immediately and need somebody to assist.<br> <br> Vodacom retentions were not able to assist and referred me to the above mentioned telephone number.
