Atrocious aftercare from Discovery - Only half of the repairs that were necessary on my car have been done

Since I picked up my vehicle on 6 May, I've been trying to follow up properly with my insurance as advised by the consultant from Renew it- Only half of the repairs that were necessary on my car have been done.

Context: After a break-in attempt on my car, I needed to get my driver's side door and lock fixed. On picking up my vehicle on the 6th of May, I noticed immediately that all repairs were not done, and I raised the issue then with the repairers (Renew It Rivonia).

Specifically, the repairs to the handle and lock on the driver's side door were not completed. (Other damages to the door were done though).

Renew It advised me to contact my insurance to find out why the repairs were not approved, since they have fixed only the damages Discovery approved on the quote.

After a frustrating process to follow up with my insurance and find out what I needed to do, I've found out the following. According to the last Discovery consultant I spoke to, upon assessment, the damages to the lock were not included in the quote Renew It sent Discovery, and therefore, was not paid by Discovery, and consequently was not repaired.

Weeks later and many calls later, it seems NET ASSESS, (the company responsible for assessing the damage, arranged by Discovery) did is who did not add it to the list of things that needed repair.

Since the door lock is one of the major damages from the break in, I'm confused about how this was left off from the quote from the assessors - especially since there were for some reason locksmith charges on the quote?

The damaged lock is a safety issue, that was raised during the initial claim, and was clearly visible in the damage photos I provided Discovery, with the claim. It's also clear in photos taken when I brought my car to Renew It on the 21 of April (image attached).

I've followed up with Renew It Rivonia, who can't do anything until discovery authorises it.

This was all supposed to be done in the first round, but trying to get Discovery te help fix the mishap is impossible. Phoning their claims consultants is near impossible, and you always get directed to a new consultant, who has no context and has to start the process all over.
