Telkom insurance cancellation

I am not satisfied with Telkom service especially when it comes to cancellation. I took a phone 2019 and contracted ended 2022. All along I have been paying for insurance but everytime when I go to them to cancel my insurance because I no longer want it, they take me to all directions and give me numbers to call which doesn’t work. They said I should go to Alberton branch because it’s where I will be able to get help like really, where did I do it? Why wasn’t I sent to Alberton onset to activate the insurance so that I know who I am dealing with or where to go when I need assistance? Why they offer something that they cannot undo? Why they want me to pay for something that I no longer need by force? Please they should just help me by cancelling it or forget about me paying it. I will reverse their debit with pleasure. Whether it accumulate or not it’s not gonna be my business. I DO NOT NEED THE INSURANCE ANYMORE. If it was the other way around they will be sending me countless messages and phone calls. Thank you.
