Not happy about piggy bank issue!

Piggy bank issue...
I thought once I earned 30 gold bars I could open the piggy bank,but that didnt happen,it said I could open it or keep collecting gold bars!? Well I kept collecting bars, but to open I have to pay $2.99????!!!!! I thought once I collected a certain amount of bars I would just be able to open the bank,but the cost of 2.99 has always been there! Ive collected 60 bars and it says its full! Im not paying money to open the piggy bank! I dont even know if you open the piggy bank do you get the gold bars????
Ive noticed from the reviews people have been able to collect more bars and theyve also been charged more!
