Issue still not resolved

Good day I hate to post something on social media and especially complaining. I really hope the right people sees this post to resolve the issue. I've took out a new data contract with Telkom in February and at the same time requested that the existing contract be cancelled. The existing one was still in month 21, but the consultant received the necessary approval after which I signed the new 2 year contract which had a much larger data bundle. To date the old contract is still active. The debit order at least is not going off, but I am worried that I am getting a surprise one day as the sim is still active. My biggest issue is the dual sim I received. I am trying to get this working since day 1. On 4 occasions did I visit he Telkom store with no positive outcome. I am on 3rd sim already as each time they offer this as the potential problem. Here are some of the case numbers I received. Case: ***4 ; *** I've also tried for assistance at the following numbers: ***; ***; 081180 What must a client do these days to get service?
