Delayed services, poor service delivery

On the 15 February 2024 I was involved in a minor accident with a minibus, I was stationary at the robot when the taxi bumped my car from behind on the back fender, it instantly also punched my tire. I could have put in a spare wheel but I opted not so that the vehicle can get assessed first. My vehicle was towed to Renew it Rivonia, I put in a claim with Iwyze and the claim was approved within a few days after the assessor had sent the report. I requested to get my vehicle back and be called in when they have scheduled it for repairs but Renew it said that they had already stripped the vehicle, alright fine, fast forward two weeks later I call for an update on my vehicle I was then told that they have forward additional damage so they're awaiting approval from Iwyze, I call Iwyze so I can understand what's causing the delay I was then told that they have NOT received a request for additional damages regarding my claim from the Panel beater. My husband then goes to Renew it the following day, then they contact the insurance then out of the blue they then have the request and they will have a look at it. Bare in mind if my husband had not gone to Renew it chances are they would not have bothered to do a follow up on their end. About a week + later they approve for the additional damage. fast forward guess what?? my car has been at the panel beater for over a month now and no work or whatsoever has been done on it, I cant even get my car because apparently it has been stripped, Renew it sms that the ETA for parts for my vehicle is 1st week of April (that would have been 2 months of them having my car at their panel beater but no action) My husbands has called the insurance a couple of times to get answers but we aren't receiving any meanwhile the courtesy car that I'm using as to go back in a few days to come. He spoke to team leader/supervisor Thandeka on two occasions she promised us we will get back to us with feedback by COB till today we are still waiting (This happened last week). I don't understand how Straight through(The assessor appointed by Iwyze) does their assessments because according to Renew it my car had already been stripped so how did they not see the so called additional damage is beyond me, I also don't understand how Renew conducts business because had we not gone there no one would have bothered to follow up and we call multiple times only to be told that Xolani, the person they have appointed for my vehicle repairs is not on site and he'll contact me when he gets back most of the time he does not contact me back and I'm the one who has to play cat and mouse with them. I have contacted Iwyze, Renew it and Straight through a couple of times and none of these parties are taking accountability for the delay nor interest in resolving this or let alone addressing the issue with us. So far the treatment we have gotten is being sent to pillar to post amongst Iwyze, Renew it and Straight through.
