NOT INTERESTED IN CUSTOMER'S VEHICLE

Good day<br> About a month ago I took my vehicle to Reeds Cape Town branch for a check up as a strange whistle noise comes from the front of the car , So for the whole day they had the vehicle for the whole day only to advise me the noise come from the rear and that my rear brake pads is worn and had it replaced. So about three weeks after and I am in peak hour traffic and the noise I hear again and yet again from the front. So I called Reeds about two weeks ago and ask to speak to the workshop manager . Werner , he answers the call and advise he needs to check my vehicle job card and will return my call.Well I am still waiting on the call.So if I do decide to take my vehicle in to their work shop will they find the problem or waste my time and money to replace parts and not even find the problem I originally had complained about.
