Poor communication

My caravan fridge is not working properly. Freezer works but fridge is not cooling. Phoned Defy on the 22/1/2015 at 10h16 to request a service. I work 45km from my house and asked that the repairer must not phone me when he is already on his way.<br> Phoned again on the 27/1/2015at 11h12 to confirm date for the 28/1/2015. Asked for the repairers number to confirm an approximate time and was told that they are not allowed to give the numbers. This was fine by me but asked that they contact Patrick to confirm. I was told that he will not be in the area in the mornings but that he does have an appointment in Greenstone between 15h00 and 17h00. I told them that it will be fine anytime between 15h00 and 17h00. Patrick phones at 12h17 to say that he will be there in 15 minutes and that he will not be able to be there this afternoon as requested. Please send me a service agent/repairer that can come at a agreed time. The service department lady told me that she did speak to Patrick but Patrick said nobody phoned him.<br>
