Extremely Bad Customer Services

My vehicle went for a Service a Month ago at Lyndhurst Auto. After making a booking two weeks in advance, when my husband got there, my vehicle was not booked and he had to wait for 2Hours before someone helped him, this happened the afternoon as well when he fetched my vehicle. They had to replace a bulb on my vehicle, which was charged for on my motor plan, however up and until today, NOBODY took the time to contact me or my husband to bring the car in so that they can fit it. I've emailed Sedeshen Naidoo on the 28/04, however once again NO feedback. I had a few things which I queried and discussed with him on the email, there is not enough space here to say what I actually want to say.I left my husband's telephone number on the email due to me only being available after 17:00, Nobody contacted him. I am utterly discussed with this dealership, and will not refer anyone to them at all. It is so sad, it use to be a great place to service your vehicle, however the experience has become very unpleasant. They charged me almost R300 for drilling 2 small holes in my windscreen without discussing it first, there was nothing wrong before at that spot where they drilled. I AM VERY UNHAPPY
