Suzuki Boksburg bad service delivery

I recently bought a car from Suzuki Boksburg. I received the worst possible service. When we got there to collect the car, it was not ready at all. It still had to be washed and filled with petrol. What should have taken a few minutes turned out to be an hour an a half. They couldn’t find the service book, the spare key didn’t work and the license disk hadn’t been renewed. I received the key to my car in the parking lot. They promised to sort it out and send it with a driver to my husband’s work. We had to phone them after 3 weeks to find out why we hadn’t received anything yet. Only then were we informed that my car was never send for a roadworthy certificate. I had to drive from Roodepoort all the way back to Boksburg to have the test done, only to find out when I got there that they were offline. The spare key still did not work and had to be returned to the workshop. I had to wait another hour to have it sorted out. They promised to send me the license disk before the end of that week. It is now 9 working days later and my emails have not been answered. They delivered the disk this afternoon, 5 weeks after the car was bought. And then their finance guy just informed me that they wrote the incorrect VIN number on the finance documents... I will NEVER again do any business with Suzuki Boksburg, nor would I recommend them to anyone. What a disappointment!!
