VODACOM WRONGFULLY UPGRADED MY CONTRACT WITHOUT MY CONSENT

Vodacom wrongfully upgraded my contract without my consent. He made it seem like Vodacom is giving away to its clients and I repeatedly told him I don't want to renew my contract and he said he won't renew it. Phoned the call centre after receiving and sms telling me my upgrade has been completed. The consultant said she has cancelled it and I will receive an sms within 3 working days. To this day I have not received any sms. The loaded the data for the upgrade wich I didnt want and my bill now is high. I have been Vodacom client since 2007 but if this ia how you look for sales then you will lose lots of customers.
