As said before, name and shame and start right here. Then contact them with a very forthright e-mail telling them what you think of their customer service, and what you have done and send them the links to your naming and shaming. You may also be able to threaten them with trading standards. But also investigate a call to the ministery of transport as the brand new wheels and tyre you bought were not up to minimum safety standards.
But TBH, you might be looking at chewing the fat on this one and wearing it, as there may be very little you can do........legally! B@stards like this should not be allowed to trade.
