I don't know if this will work with a personal transaction, but it worked for me on a getting a refund from a scam company. Open a chat message, it will be an AI assistant at first, but keep answering No to its questions until you get to a real live rep. It can sometimes take a couple of hours for them to reply to a chat message, but they will eventually, just don't end the chat! I don't get push notifications, so I had to keep checking my email for their replies. They will give you a bogus answer at first probably, but with every message state that you are dissatisfied with the help you've rec'd and refuse to close the chat. I also stated I wanted to file a formal complaint against the PP rep that was replying to me because they were not helping me (they weren't!). My chat was open for 12 hours and went through 2 different reps. But I guess the 2nd rep did not want to deal with me for his/her whole shift and gave me the refund.
