The worst company I have ever come across! Absolute waste of time. Three tyre change appointments have been cancelled. They over book garages, not with appointments they think the garage can accept, but just take your money, then try to book you in for your chosen date. We have had every appointment cancelled the day before fitting. Horrendous abuse of the customer. How dare you sit on people's money like this, leaving people with nothing for it. I spoke to someone on the phone at blackcircles and was assured this next appointment would be fulfilled. I expressed my concern about driving with tyres which desperately need changing, they are putting us in danger now. I do not care what your lousy excuse is this time, I want my money back! Do not use this company, they are a dreadful waste of time.
