A complaint and call for help

I logged a claim on the 8th of January 2024 because my radiator has problems. They requested supporting documents which is the service history ,quotations and report of what the damage is and I sent through the documents. They sent me a rejection letter stating they won’t pay out the claim because the premium for January had not gone off and that the 15 days grace period had expired. I called to complain and they referred me to client care where I spoke to Busisiwe Dywili I explained everything to her and she told me to pay the premium and they would take it from there. She set up the debit order and the premium was debited on the 11th of January 2024. I then sent an email asking them to reinstate the claim and they asked me to send my bank statement for confirmation, I did as requested and they went through my statement to tell me they tried debiting on the 21st of December 2023 I told them it’s not there on my statement and that they only debited on the 31st of December 2023. They told me they would have their IT people look into the matter I’ve been waiting since 11 January and when I call them they keep sending me through to people that just tell me there’s nothing they can do. I also tried to claim the first time because my Aircon was acting up and they rejected my claim saying it’s a pre existing condition I don’t know how they could’ve been aware of that because they never asked to send my car in for inspection so that they would know the problems my car has. The second time I also tried to claim for some suspension parts and they used the wear and tear as an excuse of which they didn’t disclose fully in their policy wording.
