Cayenne kyalami

I took my bike to Honda Cayenne kyalami for service and repairs. They failed to repair the bike for a period of 3 months as they alleged they are waiting for stock from Japan. It turned out that they were lying they have problem. They received and made me to pay for my servies and failed to deliver my bike back. They allegedly app**** for voluntary liquidation and no one is answeering their phones. My bike is still held by them and they are refusing to hand it back to me.
