Poor service

I asked my mother to take my car on behalf for service on 3 October 2018 in Hyundai East Rand mall and I was promised that it will be ready by close of business, no one bothered to call me and tell me if it's ready or not -I had to call and ask then I was told it would be ready the next day which is the 4th of October. Same thing happened on the 4th nobody bothered to update me on what was going on, around 13h00 I decide to call and check up on what was going then I was told that the shuttle would pick me up at 14h00. It's now 17h53 no one bothered to call me and apologies . I'm very annoyed because its close and it's been 2 days without my car
