Bad service from VW fourways

the service I received at VW fourways was appalling to say the least, I left my car for service, I dealt with Andrew Hall who called me when the car was done and I said I will collect it at 4:30 when I knock off, couldn't get a lift to go collect the car and when he called me again I was on a call with a client didn't take his call I immediately called back and the receptionist said he was busy he will call me back this was before 5 which is their closing time that I wasn't informed of, I waited for the call and nothing when I called again no answer, I took a taxi to VW when I got there at 5:15 I was told he left and left my car keys in a safe, this then meant I didn't have transport to go home or even come to work the next day and I mean to have the decency to text me or call before he leaves and says so we can make alternative arrangements im writing this report sitting at work with no house keys as they in the car and no transport to go home, I don't know what kind of a business u running there but I have never received such bad service in my life, I must be stranded because of an employee who couldn't go an extra mile for a client and knock off a little later to accommodate my needs? wow....
