Your best bet is to find your original contract. The terms are spelled out there. Since they set the terms, then they are required to follow them exactly. For example, if it says they have to notify you, then they have to. However, if it says you waived your right of notification, then you might have no recourse unless state law says otherwise.
Also call your state's attorney general to find out the laws concerning how long they have before they can sell the items, etc. State laws trump contract terms. For example, if abandoned property laws state that an ad must be placed or the owner notified--then they would have to do that.
You'd only have recourse if they violated their contract terms or violated state law.
I'm sorry.
