I'm not sure Amex support is really needed. I paid for a stay for 2 on Amex, while there, Liz charged the second person for their share of the stay and said she would chargeback half of what I paid.
We get back from Bonaire (August), nothing has posted. More time goes by, no chargeback posted. Alert Liz, get get no replies. Consider disputing the charge. My dive buddy and I liked it so much though, we want to go back to Bonaire. We aren't sure what the problem is (maybe they were out of money?), so we offered to come back for them to take the money off our next stay. My dive buddy pings Liz, she apologizes and says she got errors trying to chargeback via Amex (hello? send me a paypal or a check, there's other ways to pay). Trying to get this agreed to drug out over months until the dispute period was over for both our credit cards.
I don't know what the issues are down there, but there was a dutch finance/accountant person working for Liz when we were there. There are multiple ways to pay a person money owed. Liz and her husband were such nice people that you don't want to be mean or anything, especially after hearing about her health issues.
