Dormant account - funds theft

Don't usually gamble or play lottery etc. Joined on a whim (I suspect on the back of an advert). Deposited funds, not much, a few hundred. Played a few times on and off and left for a year or three. Now if I log on everything is blank, no history, no transactions, no funds. Agent first says I can make a Paia application for a fee. Then says if dormant funds are forfeited. I suspect that is theft and they cannot possibly be entitled just to bank your funds (however insignificant). Not a fan of gambling, should have known better.
