45000 Km later and still not repaired

I purchased a Hyundai IX 35 in October/November 2014 and had a Satnav installed at a price of circa 22 000. From day one the internet on the Satnav hasnt worked. I asked the service department at my 15000 km, 30 000km and 45 000km to sort this out and show me how to get it to work. On the fist service nothing was done about it, the second service I was told that the satnav was out of warranty (even though it has a 2 year warranty) despite not being fixed on the first service, on the third service only the Satelite navigation was checked and found working, which is not my complaint. I was then told by Nhlanhla that he would send somebody the following day to fetch my car and sort the Satnav, which never happened. I then spoke with Gary, the service manager/foreman, who asked me to mail him which I did on Monday the 22nd Of Feb. Needless to say, I have not heard from Gary. I would like this Satnav removed from my car and credited so I can fit something with more support and back up.<br> <br> Thank you<br> <br> Tony Koen
