Panel Beating Headache

I am not happy with the overall service I received from both the panel beaters (HJ Bosch & Sons) and MiWay claims department, especially Henk Groenewald. Immeadiately after the car was repaired for the first time, I noticed the following:

1. Gap between the bumper and the fender is noticeably big and was told that it's because salvage parts were used. This is not the first salvage bumper I had and it was done well. 2. Aircon vent is broken (see attached pic) 3. There's a funny and continuous sound coming from an engine when pressing the accelerator 4. The engine "idling/running" sound is also un-ignorably loud and quite weird. 5. Sunvisor mirror (R/F)

I immediately reported to the paneltbeater and returned the car for further inspection. For (1.) above, new bumper was replaced after a hassle with Henk. For (3.) Something was lose and was fixed. Numbers (2.) & (5.) was refused by Henk and had to replace these items myself. Now for number (4.), I later discovered that the sound was coming from the aircon. I told the panelbeaters this and they checked and found out that it was due to broken aircon pump which Henk refused to approve saying it wasn’t ue to the accident. I fail to understand this as this sound was never there before the accident and the collision was a front one.
