I have a problem with RM351720821HK. In my russian post tracking service i saw that this parcel weight 68gramms but all items in this parcel should weight at least 633 gramms. I think that the service that was in charge of sending my parcel cheated and didn't send the whole order. Can you give me details about the exact weight of my order?
