Unacceptable l

I contacted Zebra Cabs last night requesting a cab for 5am this morning. I spoke to a very helpful consultant by the name of Lucky who advised me my booking has been arranged and the driver will contact me to confirm my location. The driver contacted me and confirmed the abovementioned. This morning I sent the driver a curtesy sms confirming my address only to have him arrive 15 minutes late no apology and when I contacted to find out his whereabouts he had the audacity to shout at me and say his on his way ain't he? He then insists on shifting the blame onto the call centre saying they gave him the incorrect address when I as a customer sms'd him at 4am confirming my location! I'm absolutely appaled at the service, I find it unacceptable. There is a reason why I stipulated a pick up time of 5am
