Change the parking regulations at west quay without putting up big signs on entry, if you're going to make changes then you have to advertise that on entry for people to see. All you've done is change the signs by the pay machines.
I used that car park with my disabled son and used his badge so was free parking before the new rule. It's only because we heard other people moaning about having to pay that we checked the signs, now ended up with 2 parking charges because you can't notify people properly.
Absolute joke of a company
