So this is what happened to my friend. He bought a new Asus G56J for about RM4.2k, when a few days later he found out that his keyboard was defected so he sent it back for warranty at the service centre at Lowyat Plaza. Waited 5 months for the laptop(lol), and he claimed it last week. The staff insisted him to sign the document first before handing him his laptop, but when he got home, he found out that it was a different laptop which is like RM800 cheaper than the one he bought. Called the person in charge, and he said that there were no more stock for his laptop, so he replaced it with a *similar spec* laptop(I think its G551JM), without his consent.
So we have been going over about this with the guy for quite some time now, where he initially said that Asus does not make refunds. Just yesterday we received from him saying that we can pay another RM800 to upgrade to a G750JM.
I am at a lost here. What should I do, fellow sifus. I have lost faith in Asus's warranty service, or maybe it's just that particular centre, idk. I really hope we could get like a refund or something.

Thanks for the suggestion. On it. Does this happen a lot with Asus?
