Took my car for service today and all I got was the worse treatment ever . I came from night duty to drop my car at 7h30 By Hyundai the Glen .there was no communication about my car until I decided to call and enquire .finding out when can I come to get the car,That was 15h00,.I was told the car is still at the workshop ,I then communicated with a lady who picked up my call that I would come when going to work .But when I got there they were All gone I was never informed that they will be gone,. I was left stranded in uniform and was told nobody communicated anything ,waz asked if I do see my car around of which I didn't see it Was told Keys are krpt in the safety .
