Review Just received my balikbayan box wd tampered & contents are missing!

I had just received my balikbayan box this morning which i had sent from Singapore. I found out that one side has been tampered or opened but they covered up with lbc masking tapes. Ot was obviously opened up & some contents are missing as the sides that had been tampered was loosen/hallow! The packing lists that has been attached to it was also missing! Which means they purposely removed it from the box! So may I know who is/are responsible for the theft?!
