Will i use them again ?? NEVER !!

Took my Mazda 5 in for service and complained about my front brakes shuddering. Was \skimmed"by workshop and after about a Month the brakes started Shuddering again. Took the car in Again on Thursday and got it back on the Friday and the problem is still the same. This is a company vehicle and i am losing business every time the car is taken in for repairs. Cant believe this is happening AGAIN !! """
