Replying to Bindings or new skis?

So I have this years k2 silencers and this is my first year skiing all together...got the basics down and headed to the park....

I asked to get my bindings set centered but they didnt really feel like listening and put it to back centered :/....I didnt really care so i skiied till mid jaunuary-february and decided that i wanted them true centered...according to my friends it helps alot...and so far ive been riding way better....

Around february my heel insert/carrier for one ski kind of broke and the brakes popped out..i snapped them back in but everytime i fall/skis pop off they snap out so its not big deal..that one ski now snaps off more often but it hasnt hindered my skiing much....

Well today i did a 180 off a 10-20ft kicker and like one sec after i landed it and was skiing switch, the ski fucking popped off and i tumbled down the hill..the ski also rolled down the hill so i had to walk down :@...According to the shop its "unfixable" so im wondering if i should buy new skis all together or get new bindings...mind that ive already had my bindings taken out once and already have a set off holes on each skis.

Btw my bindings atm are the fucking shit marker 10 EPS ones
