no parts

I gave my Honda 90hp outboard gearbox to Honda marine Durban to repair. they have been very helpful, within an hour they stripped the gearbox an gave me a quote. I decided to replace the gearbox, paid full amount required for a new gearbox to be imported to south Africa. after 25 days still no gearbox available to import. I contacted various service agents, all of them gave the same reply: Honda marine after sale service does not exist and therefore they don't work on Honda motors and don't service them either due to no parts available.
