VA Auto Repairs exploiting customers

I am from Ellisras and bought a Renault Koleos for my grandson. I did an inspection on the vehicle and noticed the left outer cv joint boot was cracked. I went to my local MIDAS shop, bought 2 replacement boots. I had to go to Midrand for a week to attend meetings so called a few auto repair shops close to where I will be during the week and "Steven" from VA Auto sounded as an honest guy and knowing what to do. I dropped my vehicle of at around 08:00 Tuesday morning. They VA Auto were requested to fit the 2 already bought cv boots as well as supply and fit the inner cv boots. I got a message around 13:00 saying they have only started to strip and won`t be able to finish on Tuesday. I agreed that they can finish on Wednesday, I got another message at 10:00 Wednesday saying they are done stripping but my cv joints, both side were damaged and need replacement and that the outer boots I supp**** dont fit. I then requested a quote and was completely faberblast by the cost, very close to R10K, I only got my vehicle on Thursday. As I mentioned I did phone other repairers in the area and the most expensive quote was R5.5K and that was stripping both shafts,fit and/or recon cv joints and supply 4 boots.I sat between a rock and hard place, my car was un driveable so I had to pay. The worst part is they threw away my invoices for the "incorrect" cv boots I supp****, meaning I am stuck with them and another R860 waisted.
