You’re not going crazy! Sometimes the automated system has a hard time identifying accounts (especially if the payment email differs from your main email), not to worry though, we do see the order on our end.
Submit a quick ticket letting us know that it's not showing for you and we'll get you taken care of. You don't even have to say anything, just put the code word "MAGIC" in the message and we'll make it happen for you just like magic.
