Fantastic company let down by City linkGreat website, and a fantastic selection of sports equipment. Super fast dispatch, but let down by City Link. The running shoes were delivered to a neighbour although I was in the house ( I had put alternative neighbours addresses for delivery on their website) but they never posted a note through my door telling me.. I received the shoes 3 days later, as the neighbour forgot all about the delivery..Barrington Sport offer a fantastic free returns procedure which I have had to accept as the shoes were too tight. I am now waiting for the second larger pair. They were sheduled for delivery by City Link yesterday, but they decided not to bother and are delivering them today? We waited in all day yesterday for the delivery. When I contacted them last night they blamed the sub contracted drivers. So in a nutshell a great company let down by a courier.
