Dunc has done a load of work for me over the years and the service is always first class, he is always busy, morning, noon and even late at night and usually weekends as well. it sounds like a small oversight, and although it took you a couple of hours, he still got the job done for you and fitted you in the day you were meant to be done when he could have easily have sent you on your way since he didnt have the booking marked in the diary...easiest way to get in touch with him is by phone, if he's not there then ask alex to book you in....
