This company is not professional at all, as a customer I am so disappointed. As you say so nice, fix the outside and nothing inside.
I had several errors on the on-board computer over and over again, but this garage just was not up to fix this bug.
But now comes the summit, when I wanted to pick up my car the clerk insisted that I have to pay the costs in cash. Now hold on, the costs amounted to over 1500.- CHF, asked the clerk how I 1500.- CHF in cash to settle, he had zero understanding. The answer was, our bookkeeping has classified you as cash without informing me. A company that does not issue invoices and treat the customer like that, no thanks! Then someone should tell me that this is professional. Well, one thing I can say is that as a customer they have LOST.
