Hyundai Edwin Swales a bunch of *******

I have booked my vehicle at Hyundai Edwin Swales and have been overcharged at ransom. The company needs funds in advance to do service and along the way they increase the fee by adding additional fee like when a car is booked in and an aircon ship that needs replacing and later was told that it also needs to be re - gased and huge fee of R 750. All other quotes received was below R300 but they say the work wont be guaranteed. That was non sense as the guy that they call in charges R350. These guys inflate prices and will be reported to tribunal for overcharging.
