Telkom and Finrite can go to hell

Telkom finrite is the worst insurance company ever I had to deal with,I lost my samsung s9 about 4 months ago, I emailed everything as I was advised by Telkom, and I never got any response since then,I called after doing a follow up and I was told they don't pick up anything from the ID no and the policy number I gave them. I was then advised to send invoice from Telkom which reflects deducted payments,its been 2 months now since I emailed the invoice and there has been no response. What I fail to understand is why Telkom is doing this to their valuable customers because surely the reason they not dealing with finrite is because they have this endless problems with them but hence they take our money every month and when its time to claim they let you deal with finrite on your own and they tell straight there's nothing they can do about but the money is being deducted every month.
