Service Centre

After attempting numerous occasions to try and book my vehicle in for a service the past week, I have had no joy from Hyundai Pietermaritzburg. Every time when I phone them, the response is that the line is busy. I find it pathetic that not one person can make the attempt to phone me back. My vehicle is at the brink of going over its allowance this week, with no joy. I do not have the time or the patience to deal with this useless service. When I purchased my vehicle in 2012, they managed to lose my service book after the first service and as time has gone on, every time when I have taken my vehicle for a service I am promised that it would be replaced. My vehicle now has 75000KM's on the odometer but no service book. I think I would rather go back to VW, as this is ridiculous.
