Do AU's have a bad clutch?

[skelly]

Well about 4 weeks ago my clutch in my car was shot, couldnt go past 2,500 rpm in any gear without cluth comming on and just reving.

So 1 week and 700$ later i got a whole new clutch kit put it and it was like new, for a few weeks.

Then today while is was stopped at a give way intersection, i take of like normal and next thing i know i hear this grinding sound and then i couldnt accelerate properly.

I pulled over popped the bonnet but only knowing a little about cars mechanically i couldnt see the problem so i tried to just keep driving.

Anyway to cut a long story shot the same thing has heppened after just 3 weeks of getting a whole new clutch kit.

Now the question. Is this my fault or did the mechanics where i got it fixed didnt do a propper job of it? i mean this should fall under their problem still cause its only been under 3 weeks since it was fixed.

I dont know what is with it but i feel like paying them $700 for 3 weeks of driving aint worth it. I personally think they should fix this for free because its only under normal driving circumstances and i only just paid off the fee.

Any oppinions greatly appreciated
