Parts bought more than a week ago

I am very disappointed and totally disgusted with the level of customer care that TOYOTA SA is sought to be giving. I purchased parts from Pretoria North branch on the 25th October- AND I AM STILL WAITING!! ( and this is not the first time I'm experiencing this with Toyota SA- I experienced the same thing in January this after ordering a HOSE). So much for promoting the use of genuine parts when the the manufacturer/supplier CANNOT provide. The customer care consultant I spoke to over the phone (Elsa) told me that I will get a response from parts department within/after 6 HOURS!! The parts sales person at Pretoria North branch and his Manager have already made follow-ups on the 27th October regarding the order (HOW MANY 6 HOURS ARE THERE FROM THE 27TH TO DATE??)- If this was TRUE, I would not be penning this NOW! Frankly I am disappointed that TOYOTA SA as the manufacturer does not seem to be bothered that 8 days later after the order was placed- I am still waiting- and ALL they can say is that the parts are out of stock! In the meantime I am immobile for fear of damaging the car! Whose responsibility is it to ensure that the parts must be available especially that TOYOTA SA expects customers to buy genuine parts, and these can ONLY be bought from TOYOTA SA? The OUT OF STOCK story is not good enough for me! Why must I be inconvenienced after having paid for the items which are necessary for the smooth running of my car? This is totally unacceptable and indicative of a company which does not give a damn about its customers!!
