I echo everyone elses reviews... Repeatly booked appointments and no one turned up. My favourite was today when I had a cheery call from the fitter asking about parking and telling me he'd see me in 15 mins. 20 mins later a call from Callisen, saying that it had been cancelled. Impossibly hard to contact them. The fact that the tell you that if the customer cancels on short notice you will have to pay £40 is galling.
