cancellation request

I have 4 contracts with telkom two mobiles and two data sim i wanted to upgrade my Data sim and was told by the sales consultant that i cant i need to take up a new one and cancel the old one.I have been sent to pillar to post with the cancellation i was told i cant cancel at the branch i must dail the 081180 number and talk to an agent the agent says they cant cancel from their side i need to go to the website www.telkom.co.za and request for cancellation the website is so unfriendly It does not give me an option to cancel as it sends me back to the registration page or to dail the 081180 number Im thinking of cancelling everything as im not getting joy I feel trapped to taking two contracts for nothing I think ill stop payment for all my contract deals until this is sorted
