My recent experience was very satisfactory , I had a fault with my freezer so i had to arrange an engineer visit . To my surprise the website allowed me to do this myself without talking to an agent . At first I am dubious as to whether all this AI stuff works efficiently, anyway I booked the appointment and time and relieved notification that all had been accepted . Before the appointment date I again relieved notification of the appointment . On the day of the appointment I relieved a message advising me the name and time of arrival of the engineer . The engineer arrived on time and was able to repair the freezer on the first visit . So all I all a very satisfactory from start to finish appointment .
