That's not just dumb, it's highly improbable. Searching their database by the inscription probably is not an option available to the customer service person who answers the phone and works off a screen with limited options.I just tried that. They can only search if it has a first and last name. “Their system can’t search phrases/engravings”
Sounds kinda dumb that you offer an online option for a personalized engraving and can’t backtrack it
If you're really curious, write them a letter. Address it to someone high up the food chain. That person can route your request to a database administrator (or someone else who works on the tech side of the house) who will have no problem searching the database for "EL SQUID".
Of course, that's a long road and you've already done your part. If you just use it and enjoy it, no one can reasonably accuse you of failing to take proper action.
