Milking people up..watch out!!!

I took my car for diagnosis on the EPC light on my dashboard and I was told that my car needs to be opened up for an additional R7000 excluding the parts to be replaced. This after I paid R1058.00 diagnostics fee and that cylinder 4 is low, but against what no one could tell. This is after I told them about a throttling and loss of power that I disclosed to them. I called Metrology subsequently, I was told that the garage should be able to tell me. I consulted a person who works for VW and he gave me four possible problems and yet Barons technicians could not after paying R1058 and over above that my car does not need to be opened up. Putrid service. The timer on my dashboard is wrong after they worked in my car and car was not even hovered. Milking people for money. I was informed that to repair should cost me R2500 as opposed to the R7000 excluding parts. Never again I will ever service my car there. My service book as I checked today, it’s not accurate. I even doubt that what they ticked was even done. Such negligence when they know that a service book is so important to maintenance of a car. It is shocking indeed.
