SOME A$$ STOLE THE bracelet THAT I BOUGHT FOR 300 FREAKING DOLLARS!!!!!!! i don't know what to do!!!! I AM SO UPSET, I CRIED OVER IT CAUSE I WORKED SO HARD FOR THOSE MONEY AND IT WAS A PRESENT FOR MY DAD!!!! i went from store to mcdonalds to buy food, and i put my bag on counter top to pay for it, and BAM, MY BAG IS GONE!!! I CHECKED EVERYWHERE, ASKED THE CUSTODIANS TO CHECK THE TRASH CANS, CONTACTED THE MALL SECURITY, NOTHING HELPED. WHAT CAN I DO? DON'T THEY HAVE CAMERAS AROUND THE CASHIERS? I AM SO PISSED RIGHT NOW CAUSE IT WAS A PRESENT. CAN ANYONE TELL ME HOW CAN I FIND THE BRACELET PLEASE??????????????????????????????
