Yes I've tried..............
At first they wouldn't admit liability, as it was dark when I got the car back, and covered in the white residue from fitting.
Spotted the damage on Sat AM and phoned them straight away.
After a few snotty phone calls and a letter ( copied into Head Office )
They have offered to pay for the repair as a gesture..........
( I think Jester would have been a better description )
The damage is not too bad, but I know its there,
but there is no way they will cough up £ 700 for a new wheel.
Once its done, I will continue to shop at Costco, but will park very near the tyre bay with a "polite notice" in the car window.
