21 days waiting time for a thermostat.

Today(25/1/2016)i approached Mitsubishi Roodepoort to purchase a new thermostat for my 2005 Pajero 3.2 did SWB. I was told by the sales person that they were out of stock and so was their warehouse and that there would be a 21 days waiting period. 21 days without a vehicle due to a part of +- R400.00. Manufacturers complain about users not using OE spares,but they dont keep stock. The person then phoned head office and I was advised to place an order and then they will attempt to speedup the delivery. Meanwhile I would be without transport and I would have to pay the full price upfront for the item. I would also be at the mercy of Mitsubishi to supply the item on their own time without me being able to get my money back should I be able to source the item elsewhere. This forced me to source a \pirate"part which was available in 1 working day. Mitsubishi is useless and is a disgrace for their personnel who was embarrassed by their head offices reaction!"""
