yeap,you're not obligated to pay the agent's comission/fee whatsoever because its not you that engaged his/her service at the first place. it is the owner that uses his/her service to sell the house. the link that you provide says it all.so,don't pay.

Other fees that you have to know is stamping and legal fee for agreement/SPA. I'm not sure whether it is already included in the 2.5% as quoted by the agent. And lastly the valuation fee in order for you to obtain your housing loa later. Based on the property price (RM295k) the valuation fee should be around RM300 something.
