Frustated!

I've never encounted bad customer service than the call centre agents that work for finrite. My claim was on the 14th January 2020 and when I called they said they can't find my email nor my documents then later said they found them. You would call until you run out of airtime no one is picking up and or they hung up on you. Paid my excess on the 09 March 2020 -R750 after that I was told lies and then I would call with no answer. Money is being debited every month and I don't have my phone. This is so frustating I don't know what to do anymore.
