Bad service and even worse attitude!!

My Amarok broke down on Saturday 6June due to an electrical problem. After towing to my house I proceeded to call VW assist in Sunday morning, a very friendly technician came out on Sunday afternoon to my house to try and resolve the problem. He checked a few possible causes and could not solve it and suggested to me that I get it towed to the nearest VW so they can put it on the diagnostics. Sunday evening 7June it was towed to VW and I was told by the technician they will try to find the problem in the morning once they have booked all the services in. On Monday 8June at 11h00 I went to find out the situation, the service manager Kyle did not even know the car had arrived, he said they were still waiting for it to arrive! After him finally communicating with his technician Tony found that the car did actually arrive. Tony said he will look at the car and get back to me at 12. At 16h30 he called and said he needs to check the the valves haven't bent and the timing is right. I asked him why did he take so long and he said to me that there are other cars more important and he will look at mine when he gets time!? Up to today they have not yet found the problem! Unprofessional!!!
