Swearing at customers and refuse to give name!

Tried to cancel my Vodacom contract which is ending 22 October. Very rude guy started arguing when I told him I am going to a different service provider. <br> <br> I ask him to send me proof that my contract will be cancelled and then he gave me attitude. I then requested his name and details and he said to me I must f*** off and he put the phone down in my ear. <br> <br> I still don't know if my contract is cancelled. I phone again and it must have been the same operator as he refused to speak to me and put the phone down again!<br> <br> No wonder everybody is cancelling their contracts!!
