Marriott Business Bonvoy
Called to cancel, and the system is now automated and did not transfer me to anyone for a retention offer. Although to be honest, I did not want to keep the card anyway. I need to get under their 5 credit cards to eventually apply for something more useful.

For me, the main issue with the card isn't Amex, it's Marriott's devaluation. The 35k free night is useless in a lot of cases (for me) as almost every time I tried to use it, it was "dynamic" season and the hotel was 40k or higher.
