Discovery stone wall my income protector claim

I have an Income Protector policy With Discovery Life. I had an accident on 31 October 2024 and was booked off from 18 days. I send the necessary documentation to Discovery Life on 12 November 2024. They promised that the claim would be resolved in 3-5 days. It is now 20 days. When I send an email, all I just get is an automated response acknowledging my enquiry. When I phone they just promise to escalate it. I have made piece with it that Discovery will not pay my claim and will just ignore me until I go away. I have no other choice but to move all my Discovery products to another provider as Discovery is just plain dishonest. If I cannot trust them will my Income protector, I think it is fair to assume that they can not be trusted with my investments, life policy, medical aid and short term insurance.
