Unprofessional Customer Service

So I came in to collect a vehicle which was in for service after receiving an email to say that the bakkie is ready for collection and was told that the person who is dealing with the vehicle is on lunch and that I must wait. Nobody else could assist to collect the vehicle. This is very unprofessional coming from a reputable service provider. I had to inconvenience another person to wait for me to see if the vehicle was actually ready for collection and had to wait for almost a hour after the person's lunch break. I am certainly sure someone else could have actually assisted whilst that person was on a lunch break. Really poor customer service from the Branch in Epping, Cape Town.
