Incorrectly charged a sellers fee and nobody available on live chat

Hey all - never had this happen before. My wife sent me a Venmo (not even remotely close to a payment for a good or service) and somehow Venmo automatically checked that box and deducted a 3% sellers fee.

Whats the best way to resolve? It’s a Sunday so maybe not open but nobody answers their live chat or phone number and there is no option to refund.

Venmo basically stole $86 from us - what’s the best way to get their attention and get this resolved? Has anyone been able to solve an issue like this?
