Is it because I am a woman?

I am so fed up with Toyota, every single time I need to deal with incompetance and chance takers! Today I find out that my Warranty had expired on Saturday, according to the service agent Margeret, it expired on the 29th and when I was called to have it extended, I was told it expired on Saturday, and because it expired on Saturday, I no longer qualify for an extension of the factory warranty but now had to take out a more expensive used car warranty, which I am seriously unhappy about! Firstly because you never notified me when I called and advised that there are things to be checked on the car that is covered under the warranty, that it expires on the 28th of July, secondly, there is no way I could have checked the dates on my own as you NEVER sent my policy documents after the previous extension. I refuse to be penalised for a mistake you made. If it's not you trying to tell me I need to replace brakes and wanting to charge me R 3000 for it, when in fact they were still in perfect condition, or not washing my car after a service, it's this, and this is the most serious one, because of your failure to deliver a service, I am being penalised.
