I am playing Pet Rescue on Facebook and earned 50 gold bars in the piggy bank and was advised to redeem them for gold but when I clicked on the piggy bank all I got was a menu to PURCHASE THEM. I thought when our piggy bank reached 50 we received the free gold. I clicked on the top button in the purchase window and was charged for the bars. I haven't even put in payment information on the game but my banking information must have been made available because the purchase went through debiting my card. Could you explain how the piggy bank works on the game again?
