Bridge has been processing for 48 hours and support just keeps sending me canned responses

Bridged ETH from Arbitrum to Base on Sunday. Transaction confirmed on Arbitrum, nothing arrived on Base. Explorer shows it went through on the sending side. I've submitted a ticket, I've checked the bridge's status page, I've done everything their FAQ says. Support replied twice with the same copy-paste message that doesn't address my situation at all. At what point is this just gone and what do I actually do next?
