Very poor level of service - simply failed to fulfil what they sold online regards the ability to fit a set of tyres with a mobile fitter on the date that was booked and promised. I required a set of tyres to be fitted that week, ordered on the Sunday and given available slot on Wednesday for fitting. Was emailed on Monday to say that slot NOT available, but Thursday morning was however. Agreed to this change. Was emailed late Wednesday evening once their phone lines were closed to inform me that fitter was unavailable to fulfil the Thursday appointment. Very late notice. Email stated that only availability was for Saturday, which was not suitable at all. Tyres had to fitted by Friday. I emailed to cancel. Ridiculously hard work to cancel, as emails apparently go unread and stock replies seem to be sent out, regardless of the customer input. When I cancel you simply have to reply " yes sir, straight away sir, apologies for failing to fulfil our promise to fit your tyres on the promised day - here is your money back" It's that simple. Don't waste my time with superfluous emails, which then require me have to phone you just to get some sense, and a clear acknowledgment that you will cancel and refund. My experience - Blackcircles.com are hard to trust, unreliable, late with pertinent information, and then when cancelling because of their poor service it is more of an ordeal that necessary. Very poor customer service indeed. I would not recommend.
