Cancellation of cellphone insurance and reimbur*****t of funds

I’m having problems canceling my celphone insurance contract with Finrite and tellkom.

I wrote an email to them in November asking for my insurance to be canceled which they acknowledged, and Letlhogonolo Gaethusel (Finrite customer service agent) from Finrite emailed back in response, confirming the cancellation of the cover. However they are still debating me every month. I’ve called telkom several times and I was advised that Finrite has to send me a confirmation letter stating that the insurance has been canceled so that I can be reimbursed, I then sent an email once more to Finrite and Letlhogonolo rep**** back, asking for my January, February and March invoices so that she could escalate the matter to Telkoms billing department. That was the last time I heard from her. Letlhogonolo has since stopped replying to my emails. I received my invoice from telkom this month and I see the cover is still there.

I would like Finrite and Telkom to stop debiting me for an insurance cover that I canceled months ago and I would also like to be reimbursed every cent that was deducted after the cancellation of the cover, As I have proof and a track of emails from Letlhogonolo Gaethusel (Finrite custumer service agent) confirming that the cover has been canceled.
