Bad service from PG-Glass

I am writing to you to express my disappointment in the resolution of my recent motor glass insurance claim with PG-Glass in Nelspruit. I took my car there on Monday 14 May 2018 for the replacement of the front left door window. PG-Glass didn't have the correct colour of tinting for my car, although my car is stock standard. They assured me that they would fit the clear glass, order the correct tint, and get back to me regarding tinting it at a later date. When they told me that my car was finished, I noticed that my door spring was loose, tabs were not correctly replaced where they removed the door panel. On my way home, I noticed that they forgot to connect my electric window switch. Once I arrived home, my son couldn't open the door from the inside because they didn't connect that either! Further to this, they hadn't cleaned the inside of the window channels, so the window sc****s on old glass when opening or closing. I followed up with them on Friday 18 May 2018, and they said they can't find the correct tint to order for my stock standard 1.2 Tdi Polo Bluemotion! They wanted to replace the front two windows with the same colour, but that would leave the back windows a different colour. I'm not happy with their service!
