Ridiculous and intentionally false quote

I took my MacBook Air in to the Cavendish store. It had bought it not even two years ago when it started to make a strange noise. The iStore sent it in for assessment, and came back to me with a quote of R10 000 to replace a bunch of components that had 'liquid damage'. I took my laptop to a private company called iRestore who assessed it and said there was no liquid damage whatsoever. The quoted me R1500 to replace the fans, so much more reasonable. The iStore really just takes advantage of people and lies to make as much money as they can - greedy and unacceptable!!
