Incorrect billing, failure to deliver on order

I have an expired Telkom Mobile contract and had to log two cases in two months to correct a charge of R349 per month for an add-on internet bundle - case ***1 refers. The first agent I spoke to in December promised it would not happen again but I just got charged again in January. I have now been advised to go in to a branch to cancel the Internet Add On service I never requested. Secondly, In November I ordered the Smarthome Premium package, which also includes a two SIM cards. The order number is ***A. One SIM card works, the other have not been activated and shows as being incomplete on Telkom's OMS Ordering system. After 3 visits to the branch and multiple calls to 10213, 10210, 081180, 081183, 081187, *** (probably 50 calls personally and from a Telkom mobile branch) I have now given up. The person at Telkom who were supposed to activate the SIM cards made a mistake and no one seems to know how to correct the mistake. I am lost for words to describe the frustration I have to endure in dealing with Telkom.
