Bad service

<p>on 06/10/2016 my BMW X1 went in for a service , I requested for my left hand light bulb to be changed and asked for a quote before any work is done , I got a call saying the quote is R14793.27 for the service so I said that nothing must be done so I got told I have to pay R1000 for the diagnostics that was done to find out what is wrong with my left hand light after I told them to replace the bulb. When I arrived and queried this I got told that it's a diagnostics to fix a wire for my 12v socket in my boot. I then got the break down of the total quote and on closer inspection they realized the right hand lights bulb is loose and the "spring" that hold le it in place is missing so they wanted to change me R6858.84 to fix that and me not being a mechanic of any sort knows that the light is a sealed unit and that spring can't just be missing! So on Saturday 08/10/2016 I decided to look for my self and in 30min I found the aping in the light and reinstalled it. Now if I said go ahead with this service I would have paid almost R7000 for their mistake?</p>
