Inflated pricing

I just took my daughter's 2012 Chevrolet Spark to Williams Hunt Fourways as there was a problem with the wheel bearings and have just been quoted R6k to replace the 2 back bearings. I thought that this was excessive so called to find out the cost of the parts and it would appear that if the as quoted the parts are R1.5k then the labour is R4.5k. On complaining I was told that they charge R1k per hour labour. On top of this she was also told that the brake pads and brake shoes needed replacing at another R2.9k. Total R9k. You don't have to replace brake shoes. Having now got other quotes it would appear that Williams Hunt have inflated their price by some R5.5k. Disgusting!!!!! Do not ever use their services. They are a complete rip-off.
