Telkom's Difficult cancelation process

My cellphone contract came to an end in January 2020 , however 7 months later I'm still struggling to cancel my contract . I've app**** for cancellation 4 times already and all they do is tell me it takes a while for the cancelation to be effective. I'm disappointed in the service received over this period and no-one can tell me why it has not been canceled . Agents on the phone say to go in store and when you go in-store they tell you to call in to customer. Their service is pathetic and its been coming on for so long its basically adding on another year of what was supposed to be a 2 year cellphone contract. I'm so glad I chose to not upgrade with them and chose a different network.
