Bad service when claiming

It's already a bad sign that I am here again for complaining about Discovery Insure, but It's seems like I have to, every time I have a claim with them. I put in a claim for my car late January 2023, and yet today it is still not addressed. Their consultant sends emails but is never reachable on either emails or calls. The cause of delay is based on the following: 1. Their assessor instructed the repairer to repair the bumper of my car after the January incident, after I had told him that they had previously attempted to repair the bumper and iy cracked after few months without impact. I escalated this to Discovery and there was no response. 2. They somehow book my car in for repairs and leave out the rental which I am paying for, I have indicated to the consultant that I will need a rental but he never responds.

It's almost six months now and there is no way forward.
