The mythological fragments of the event have not been sent

I hope the administrator can help me find the rewards I deserve  I unlocked all the anniversary celebration activities on the Belgian server, but I didn't get the mythic fragments

There was a bug in my game during the anniversary event. I claimed all the rewards in the Billy time zone and found that my 150 mythic fragments didn't arrive, but the event shows they have been obtained. Please deal with it quickly ！！！！！
