Poor workmanship

Not very helpful. Car went for service. No problems. Ladies very friendly. But then my car comes back. With a squeaking noise. First I am told it is the cambelt. When I stated that has been done suddenly it is a different story. Now it is the diafram on the oil filter adaptor. Another huge quote later I am expected to pay for something that was not a problem. Will surely not reccommend them. But the ladies....spectacular service and very presentable.
