Blackcircles UK/Customer service (not the garage fitters): I ordered just mail order tyres, no fitting, on a Saturday (staff are there), and the tyres were due to arrive on Tuesday. On Monday at 12:33PM I got an email saying the tyres were out of stock! I was offered a very similar tyre for the same price (it was normally overpriced, so pretty much the same deal). I replied to the email saying I will accept the swap, but needed to know when I will get them, assuming I won't be getting them tomorrow (Tuesday) any more, but 4hrs later, I have heard nothing more from them, and they have not given me a phone number to call! I tried to call them on Saturday because their website's payment system was down, but no one answered the phone, and I was on the line for 30 minutes! I recommend you compare prices from your local tyre place - I have found 4 better tyres locally that are cheaper now, but Blackcircles have left me in limbo all day. Only use this company if you have no time constraints, don't mind being let down at the last minute, or if you are 100% sure they're the cheapest.
