Fixed my car without approval and expect me to pay

<p>I happily bought my Mercedes-Benz my CLA 220 mid last year with Mercedes-Benz Centurion. I then started experiencing a problem with the car. I took it to Mercedes-benz Centurion as I did not understand the problem. </p> <p> </p> <p>I requested me to bring it in for invistigation. They told me investigation is at no cost, they will only charge should I want them to fix the problem....I said okay. They then removed every inside part of my car. After a day they called telling me what the issue was.. which Glassfit was responsible for. Glassfit came to fix the problem. Mercedes-benz Centurion then told me even though they did not fix the problem, I have to pay R7944.60 for them to put back the parts. </p> <p> </p> <p>I then told them...</p> <p>1. Should it had been at a cost to investigate, they should have told me before touching it!</p> <p>2. Why did they remove parts of my car knowing for them to put it back on they will be charging me</p> <p>3. I do not have money to pay...money is something that one has to save - should they have told me before touching it I would have told them not to touch it</p> <p> </p> <p>They still have my car - which has been 3weeks plus - saying they will not give it back till I pay.<br />Last week, 4th April 2017 they sent me an email with a qoutation - the one they should have sent before touching my car asking for permission to go ahead with the repairs. - which I do not understand as the problem has already been fixed by glassfit at the Mercedes-Benz Centurion premises. </p>
