Absolutely useless, from what I can understand BlackCircles will happily take your money even if your chosen and paid for tyres aren’t available in stock. My fitting appointment was cancelled by BlackCircles and I was asked to rebook, no information as to the reason, very inconvenient. Rang my selected garage to find out what was happening, advised only one tyre had been delivered, having ordered two, what was the point in delivering one I have no idea. Contacted BlackCircles customer services via email took over 72 hours to get a reply, woeful delay and f#cking annoying to be honest, having been inconvenienced. Had tyres fitted elsewhere in the meantime due to having no communication. Don’t waste your time, book your tyres elsewhere, to avoid a stressful experience.
