ad service from FNB life

I am trying to sort out my claim for almost a year now. I wrote may many emails to them, I went to an FNB branch and the lady there also send an email to them. No reply from them, then they started sending me mail to say they need more documents. I have sent t per email and on my app. Still no result. I tried to call them and was put on hold and nobody came back to me. I stopped the payments but the debit order still went off 9 times.
