Toyota Warranty Dissatisfaction

I would like to, once again, express my displeasure, with the assistance i received from Toyota, especially Krugersdorp [Wesrand] Toyota and Toyota Head Office, after my basically new Toyota XS, broke down, leaving us stranded next to a highway. I had to get Toyota Assist to come lowbed the car to Toyota Krugersdorp. With 50 000km on the clock, the clutch packed up. Toyota Krugersdorp told me that it was wear and tear, me not using the clutch correctly or all the uphill in our town! When I took the car for a service before this incident, I told Randfontein Toyota that the car sometimes battle to change gears, but I was told that everything is in order. I took out an extended warranty to have peace of mind when something happens but was told by Monument Toyota in Krugersdorp and Toyota Customer Care that this warranty will not cover the costs. so why then did I spend money on this so called extended warranty? I am a pensioner and had to pay over R15 000 to have the car repaired. Eventually I was told it was wear and tear....at 50 000 km? I have always driven Toyotas and never experienced a clutch packing up so quickly. I even took out a service plan from Innovation Group and was shocked when I was told that this also did not mean anything! When people buy cars, they are told about this and that like extended warranties, which costs a lot of money, but when incidents like this happen, basically nothing is covered. At present I am a very dissatisfied customer of Toyota and would like to share this with anybody considering to take out an extended warranty or even buying a Toyota.
