I got email confirmation of refund eventually, so all good, I will keep my current tyres for the time being and just keep an eye on them.
The thing with black circles is the service all depends on the fitters, although the fitters had my tyres I believe, they should have confirmed that and given me a time slot, due to work I needed a time earlier in the week for next Monday, to sort things out, I shouldn't have to chase them up.
Anyone though of a better place to get tyres for future reference?
