How that ticket was answered appears to be fine to me. They most likely looked into the account, saw no issue with the crates itself and passed it along further to a dev to look at when they have time.
Again, as your friends/guildmates had no issues with the crates and I have not seen any other reports of issues with the crates you most likely just had bad luck with these crates and it’s not an issue with the crates themselves.
They looked at the account/crates, saw nothing broken and passed it further to be looked at. I’m not sure what else you’d like done for this situation?
