BRD Automotive Service Centre

nice little husband and wife business,took car for a check over and service as was a recent purchase.Told the car was good ,the drive and airconditioner belts were replaced as were plugs fluids etc,the squealing noise was still there after new belts ,realised it was a pulley.Now car is at specialist in Hornsby having all the suspension bushes replaced as well as the pulleys the big problem I have is that I was told it had been checked all over as I had asked, and was fine ,that cannot be true as they had to have seen the state of the suspension ,now the $450 to put the belts on is being spent again as well as $3500 on the suspension.I am disappointed as it appears I was lied to and I believe that an apprentice must have done the job on a car that requires some expertise not a boy learning the job,I will never go back and would advise anyone to avoid BRD Automotive at Lithgow I rate them as very bad due to the fact that major safety issues were had and could have led to someone dying in a crash,how can you find a trustworthy,honest mechanic?
