Toyota your service SUCKS!!!!

I have a 2016 Hilux GD6, at my 90k service I was advised by Toyota that my exhaust manifold was warped, they recommended that it be skimmed and a new gasket installed, this was done at my own cost. At 133k the gasket has blown again. Toyota Tokai was contacted, they were of no help saying its not a problem of Toyota's the bolts were not torqued properly. In my opinion then its a Toyota problem as this was wrong from the factory then. Alvin the service manager just brushed it off and said I must replace the exhaust manifold. Toyota SA was contacted, the lady that took my call was very helpful, but there has been no response or feedback from them. Toyota this is what makes me think of a different manufacturer next time I purchase a new vehicle. This is my 4 Toyota and probably my last.
