I was hijacked at gunpoint at Steenberg station, my bakkie was recovered in lavender hill. I got the bakkie back, found I had problem as engine was changed at 41 000 km by Nissan. So they told me to come 2 months before the disc expired, which I did.The cops wouldn't give me a clearance certificate as there wasn't the new engine number on job oder from Nissan. Nissan changed their computer system 5 years ago. I have been fighting with them for over a year, to no avail. The other day I went to Muizenberg police station and my case number has disappeared from their systems. I am lost as I don't know what to do. Funny thing whilst I was the station, I got a fine for expired license disc. Please can you give me advice. Thanks
