I'm paying for something that has been paid for a year ago

Telkom mobile is debitting money from my account every month for cellphone insurance of a device I no longer have in my possession for almost 2 years now. I wish they were transparent enough when I did the renewal for a new contract that I could cancel or transfer it to the new device as my new device has no insurance.

I've been contacting Telkom mobile back and forth in anticipation of wanting to cancel the insurance but no proper assistance. I've been on several calls bought airtime to be assisted but lines are cut off during conversations and while being transferred to various departments.

When I eventually got transferred and left a message for a call to be returned, I've been told that nothing is show ing on the system? How is this possible but debits are going off?

I've then been told to contact Finrite the insurer, just to find out that they don't do insurances for Telkom mobile any longer??

Now tell me how can monies be debited each month but nothing is found on the system...

This is ridiculous and so frustrating.
