WORST SERVICE EVER!!!!

I sent my car in to Hyundai Bedfordview on the 19th of June. If you have a white Hyundai i20 then you would know that they have a factory fault where the paint peels. So my car got taken in to be repainted and I was told it would take 10days. 10 days passed and I heard nothing. On the 12th day I phoned to check for an update on my car, had to leave a message and no one got back to me until a day later. Apparently the person dealing with that part of the job left and someone else by the name of Thuli took over, I asked again for an update and she said she will get back to me, which she didn't and I had to yet again chase after them. I kept phoning but as soon as I ask to be put through to Thuli the line just rings and eventually I get cut off, so I phoned and left a message for her to get back to me. She only gets back to me on Thursday saying my car needs to get yet another quote approved because it started peeling on another area. I asked why they couldn't atleast have the decency to phone me and keep me updated on what's happening because I was promised 10days and had to make alternative arrangements to go to work and get home which is costing me alot, to which the response was that she is trying to catch up with the last persons work.. I phoned in again yesterday 10th July and no one answered the phone yet again! This week will be 4 weeks that they have my car and no one can give me any indication as to when I will get it back. It is extremely frustrating because they don't even offer me a courtesy car as it is a factory fault on thier side. To say that they are unprofessional is an understatement, dealing with them is a headache! If you promise a customer a service and you cannot deliver on time just have the decency to keep said customer in the loop. It isn't my job to now run after them for answers. I have my own job to do which I have to now take time out of to try and get answers from the people who cannot even be bothered themselves. That management in that place is actually the worst. I would never recommend them to anyone. When will I get my car back? No one knows, not even the people that work there. They better get their act together because their service is just atrocious. It puts me off the brand.
