Novel Ford Paarl disgusting service

Good day, I phoned Novel Ford Paarl last week to book in my car to look at something they have fixed, but the car is doing the same thing that they apparently fixed. I told the lady, Desiree that I want to book it in as the last time they had my car for a week. I cannot afford to be without a car for long. She confirmed that they will work on the car the same day if I make a booking. So, the car was taken in on Monday, and we are still without a car. If I phone, they just say they are still busy. I have phoned 2 times already today, without someone to assist me. The people are busy all the time, and I leave a message to call me. I have been waiting for 2 hours now for someone to call me. They seem to have no consideration for the customer. They phoned on Monday, to ask if they can repair the windscreen which has got nothing to do as to why the car is there, but for what is really the problem, they cannot get back to us. This is a disgrace, and it is not our 1st encounter with them. For the last time the same thing happens.
