Having similar issue and kept getting an error when trying to submit my ticket.
Purchased coins for the Warbound Crusader Hypercrate. Got the coins and went to buy the hypercrate. It subtracted the 5500 CC from my balance for the hypercrate, but it errored out without ever actually giving me the hypercrate (or putting it into the unclaimed items section for me to claim it).
Checked my ledger and it went through...but I have nothing to show for it. :mad:
Gave me Error Code 16 (in the cartel market)
