No communication or feed back

Someone drove into my car and I submitted a claim. Discovery gave me a panelbeater that is in my opinion below there so called standards, and here are the reasons:

After they said it would take two days, it sid not. It took about a week and a half, and every day I phoned them they said "tomorrow". Then tomorrow I would have to phone them again to ask for an update, instead of them phoning me and giving me an update. They never called back when they said they would either.

On the day I could fetch my car, the door that they fixed wasn't even lined up properly, there was a different color paint stain on my other door as well. The next day I found out that my door can't even lock. I am now driving with a door that is unlockable and my car is at risk. Discovery has not yet come back to me regarding this after numerous mails and social media attemts at some form of communication.

The inside of the door that they worked on was done extremely poor as well, the material does not line up as it should, and there are dirty hand marks all over the inside of my car where the work was done.

Discovery is not getting back to me and it has been a week now. For a company that is so called "the best" I am very disappointed. The premium I pay a month is nowhere close to the cheapest option out there, and "paying for quality service" carries absolutely no truth here.
