Danmar Autobody *****s its customers

Ive never seen nor received such appalling service as I did at Danmar Autobody Ophirton, twice for that matter. First time: I took my car in for repairs as my broker advised and it there was a slight scratch on the tail light and a bigger one on the bumper upon me taking it for assessment I was a told that the light has to be replaced even after I said this just needs to be polished and they were adamant on thee change, was later notified that the replacement part was ordered and they carried on with repairs and when I picked up the car I was told that that's a new tail light that was fitted, days after taking the car I saw that this is the same old light as it has paint droplets from my old home repairs. called them and they confirmed changing the light and only when I requested to see my old light and prove the paint droplets to them did they apologize and confirm not changing it and so they came to my workplace to replace the light. 2nd instance: My broker recommended and my repairing my very small bumper bash at Danmar and upon me dropping off my car after assessments also where they said my bumper needs to be changed and not fixed this was on the 15th of March when I dropped it off 4 days later I received confirmation of replacement part being ordered and dead quiet thereafter, they again fixed my old bumper and did not replace. it now the 10th of April 4 days shy of a month since I left my car with them and mind you all this time I'm using a rental car that I'm paying for. on the 5th April only they ordered a new bumper I wrote a complaint that fell at the helm of a very rude and arrogant Gerhard who dismissed all points I made and just said "Ill get my car back what more do I want him to do" I was again told my car is ready on the 9th of April and when I got to their premises this was not true, after all the monies wasted on car hire and wasted trips for a month I asked them for an excess waver as all this was unnecessary and all financial implications and Gerhard said no. Gerhard also aggressively questioned me what did I want him to do about my car when I went to the site on the 09th which made me feel very uneasy.

If they can de***** one customer twice, what more do they do to the rest of their customers?
