Hackers are getting better...

Dear Reddit, One day I was minding my own business cutting yews in seers village not talking or anything so suddenly anything that was running java closed I know this because I was playing minecraft at the time while afking so I log back into runescape and minecraft thinking nothing of it and about a half hour later it does it again but only with runescape so I try loging back in and it says I haven't logged out of y last session I think oh since it crashed I'm still logged in but after 3 minutes I panic I go and change my password on a different computer by it was too late my dragon chain, legs,boots,helm bgs my dragon axe and a few mil missing along with some other values it added up to around 9 mil and I wanted to quit but I went to the forums and posted about this and jagex refused to give me anything back do I thought maybe reddit could spare me some money for most people 9 mil is nothing but please it's all I'm asking thank you for your time and keep your account safe :( btw my account is dog51848 ps I haven't recovered much yet I've only made about 200k
