I don't want my money card..under 16 as well.?

Okay so i changed my mind on having a walmart re loadable money card.i don't think its right for because i don't have job nor part-time (because of the fees)and I'm under 16...what can i do? honestly i never thought about the consequences and i a bit frighten about the liquidation fee there only 30.00 bucks in it. The reason i got it was because i need to buy want something online (I guess all teens do)
