Parts Pricing *******,double price of actual agent

Pricing of parts '2x' double of vehicle agent charge. <br> <br> After getting the bill for R4320 for spark plugs and R2500 for AirFlow meter (Alfa 156) - total bill R7774.80 & being refused to view actual agent invoice for the parts, i called the agent (Arnold Chatz) spare parts division they confirmed that original parts cost half of what was charged. <br> <br> Bill was dropped to R6200.00 after contesting the bill.<br> <br> As I still haven't seen original parts invoice I'm assuming Car Service City didn't purchase the original parts from Arnold Chatz.<br> <br> Have tried to make contact with Car Service City via Facebook to discuss, no call back or email back.
