Missing reward - Winter 8 Pack

Hello. Your game store have a serious BUG!!My id is 771058352729890816. I spent 8000 fc points to open the “Winter Sale Box”(which is limited to open 8 times), and your store shows that there is no items will gain twice. I open this box in two days, the first day I open 5 times and the second days I open the last 3 times, the last 3 times which is the most important items of this box, but it all repeat, and which all trash items. You can please go to check my account purchase history and you will see. I spent 50+ dollars for 8000 fc point and I got whole trash items. Please take it serious, thank you!
