if you dont know the bank pin, the only thing u can do is talk to who ever set it on there, or wait the 2 days, or guess at it, thats the only things u can possibly do
you could, power mine, wc and just drop the stuff, uhm watch people pk(i do that alot), uhm not very much stuff u can do
It looks like you're stuck, my friend. I'd just simply watch other people PK, I suppose. There's nothing much you can really do. I'd suggest picking flax but seeing that you're currently not a member that wouldn't be a possibility.
You could actually head out and try to earn money to afford a full month of members, that's certainly something I'd do if I'd ever be in your situation.
Hmm you could chop willows, just ask a friend for the rune axe or you could go to the mining guild and deposit it in the deposit box. You could also power mine or power woodcut. The final suggestion is to make a new account or not log in. (I would not reccomend logging off)
Erm, possibly train your thieving? That's always good. Just do master farmer, die, run back, etc.
Or. you can powermine/fish/woodcut.
Looks like you're going to be a bored kid for 2 days.
OR
Go outside Always good.
