Michanic What a *******!!

What a disgrace!!!! Mechanics arrived looking l guys from a s****yard. Done a so called major service, working with dirty clothes, not checking any brakes, handbrake,battery terminals or washer water levels.Spill oil on engine cover and informed me that engine needed to be flushed after they replaced the oil. Booked a request to check the vehicle because it is overheating. Find a burst water pipe but have to make another appointment to come back to replace it!! Advice from them is not to drive the vechile!!! Hello I complained about the over heating!!! Why will I drive the vechile!!!
