Bad Service

I went in Saturday just to buy spares (Brake Pads-front and rear, front discs) then I was convinced by the company to fit them through their workshop. Fortunately I decided to check the vehicle before I made payment only to find that everything was fitted besides one of the discs. The reason I got was that they forgot. When it was time to pay, the parts were now at a higher price, the salesman claimed that my vin number brought up the incorrect parts which were cheaper which led to me now paying more than what was initially quoted.
