Car at dealership for over a month and still no feedback!

My wife sent her Citroen into the Boksburg Citroen dealership due to overheating. They stated that they needed to import the parts which would take between 14-21 working days (understandably). We sent the car in around the 01st June and submitted a deposit payment to them around the 03rd/04th June. They stated that they ordered the parts around the 06th June. To date (today being the 10th July), we have still not heard anything. Two weeks ago, they said the parts will arrive last week. We asked about it at the end of last week and they said they will get back to us. We have still heard nothing back. They have offered no explanation or loan car or anything and we are unfortunately driving each other to work daily on the back of a bakkie (yes, in the middle of Winter!!) and we are really getting frustrated now at the delays and lack of feedback! Either fix our car NOW or give us a loan car in the interim if there are problems with the importing!! I will DEFINITELY not recommend Citroen to anybody!
