Trackpad issue and warranty

Hi Everyone,

Just hope for a friendly advise. I've got issue recently with my Macbook Pro's trackpad. It stopped 'clicking'. In apple store they tried to replace it at once, but later told me that trackpad is soldered instead of being mounted with screws. I had to leave it for repairs.

Today someone from apple called me to inform that a coffee been spilled to the trackpad. Therefore i have to pay AUD 118 for replacement.

I *never* spilled a liquid to that laptop. Overall, this case is getting really frustrating.

I've got this laptop as ex-demo from Dick Smith but it was sold as new, covered with warranty. Also, i've been to apple store with trackpad issue previously. They 'adjusted' trackpad but noone told me that liquid been spilled to it.

To summarise, my question is... Is there a king of 'dispute resolution' process with Apple? It gets really wrong with the 'spilled liquid' matters.

Thanks
