Crystal Fusion - A ****

When I purchased my vehicle from Hyndai Boksburg, I elected for a windscreen protection plan (Which costed me R2 256.06). I get 4 top up for a period of 2 years. My car was due for a service & Crystal Fusion top-up. I took the car into Airport Park(Kempton) & the dealer by mistake left the bottle of the windscreen protection. It was topped up with WURTH WINDSCREEN CLEANER, which cost R21.89 Why do you pull the wool over customers eyes by selling a patent product, but deliver product from Midas?? RK Moonsamy
