Terrible experience with Customer care agent!! :(

Terrible experience with a Customer Care agent. Extremely rude, hung up when we requested his name and surname to report him. Was calling on behalf of my father to cancel his contract as he is unwell. When I complained about his service he told me I shouldn't even be talking because I'm not even the account holder. Oh no, this has totally tarnished the brand Vodacom. He told me I called him so I should accept the service . I told him , no, I called Vodacom for assistance...not 'him'. Not professional at all. Vodacom what's happening???????????
