Alfa Trio Panel beaters ignore customer complain and don't even deserve one star!!!!

After an accident the Santam Insurance authorized Alfa Trio Panel Beaters to repair out Izuzu Bakkie. Alfa Trio Panel beaters was ask not to use Chines / Pirate parts and they have insured us that they don't use Chinese / Pirate parts. We got the Vehicle back and first thing the bumper was not original to the make of the vehicle so the paid to us the money that they charge the insurance for us to find the correct bumper. After a month or two we had to load stuff on the bakkie and as normal someone will stand on the tailgate and do the loading. Then the tailgate bent in under one persons weight. My husband went to Alfa Trio Panel Beaters and ask them why didn't they put on an original part. They then said they will replace it when the find one, Santam Insurance was notified about the incident and also send a messages to Alfa Trio that they must replace the part. My husband keep on phoning and ask about the tail gate and every time the promise was made that they will find one and replace the poor quality one they put on. The Insurance send out a second messages to Alfa Trio Panel Beaters on 21 October 2022 and my husband also keep on calling to ask when the tail gate will be replaced but up to date they just ignore us. The tailgate that they put on is now in such state that it is difficult to open and close. Alfa Trio Panel Beaters also worked on my Kia Rio and after 6 months I noticed that the front fender that they replaced was making a big gap and when I went to them they said that's not their problem because when I received my car back I signed that I was satisfied with their work, so I just leave it there and still driving that way, but with the Izuzu it's a different story because they was informed about the poor quality tailgate and they said they will replace it and up to now they have just wipe it underneath the carpet and we cant do anything about it. It's really terrible to get this kind of service after we have support them for many years to do repairs on our private and company vehicles. We will spread the word and will also report the matter again to the Insurance with photos of the tailgate. The old tailgate was on for almost 20 years with no problem at all.
