Mitsubishi do not carry sufficient spares

I have a 2009 Mitsubishi Triton 2.5 diesel. that blew the whole cylinder head at 173K when the timing belt broke. I have now been without the vehicle for 6 weeks as nowhere in South Africa can I find new inlet and exhaust valves and they were all bent! <br> <br> How on earth can that level of customer service be possible in this day and age? In the whole country they do not keep spares like this is surely idiotic and a complete lack of customer care.<br> <br> I will have the vehicle repaired soonest and sell it at a loss but this will be my last Mitsubishi after owning 8 of them over the past 30 years.
