Poor service cancel contract immediately

I will not stop up until this contract has been canceled. I had a vodacom sim card 5 years ago that sim card has not been in use the phone was ******. I cancelled the contract and they couldn't even pick up the sim card i set at west gate mall on a Saturday for 2 hours holding to speak to cancellation. The staff members then said i should call the call center i tried but still cant cancel they sent me a laywers letter to pay 800 and i paid and asked them to cancel they still didnt cancel. Now they sending summoneds after me this is after 2 years what do you want me to pay for you can see the sim card is not in use u can see u blocked it why must i pay for what reasons im taking this to the ombudsman you are poor poorest service provide ive eva dealt with i will never recommend vodacom to anyone i will never be a client for vodacom.
