Sorry to hear that you used those useless wnkers at Fell's, I took my 2nd car there (a rover 100, read metro, in blue, with body bumpers etc), to get rear left wing replaced and sprayed as it was starting to rot.
First time I went back they hadn't done anything.
Then they'd painted it AND the window, AND the rear screen, useless git,
Back again, and colour has completley changed, I mean it is mean't to be blue as in near sky blue and they had done it in like ocean blue (colour of darker blue on forum header), and they had torn the wheel arch liner, sheared the bolt that holds the sill protectors on and scratched the rear bumper to the point where most of the rear bumper on the left had lost its paint due to flaking and peeling (was mint when it arrived).
Total total incompetant wasarks, did it myself in the end, got full refund for what they had done, but still left with a damaged car (They later payed for rear bumper to be resprayed by another paint shop).
Is the van driver not paying??
And it sounds like they have just used a grey of some sort maybe mixed with a bit of blue to bring it up. Should have used metallic paint.
Seriously, you have paid (probably a lot, have just been stunned by the fact I have saved myself £270 on the price of spraying my newly acquired bumpers, thats when I have spent £60 on paint!! and its a damn fine job now, really quite perfect!!) to do a job they should do it, if not take them to small claims court etc.
I have sprayed metallic before on a saab 900 (was sort of silver and blue and grey at the same time, never figured out which), 2weeks and £80 of paint later I had a match and it was absolutely on the money!!! Very pleased with it.
