I returned my wheels and explained what i wanted done, and the tyre shop i went through were happy to send them back.
I also stated that if my problem isn't fixed within the next two weeks they can have their rims back, and i'll expect my money back.
So now i have to wait and see...
Also, do they charge for centre caps?, because when i recieved my wheels, the first and second time, it never came with any.
