American Express Business Explorer® Credit Card Bonus - existing card holder - DJ Amex

[alect]

I need a business credit card. I want to apply for the American Express Business Explorer® Credit Card which has a current 100k bonus, but excludes current Amex issued card holders. I hold an Amex DJ. My research tells me Amex DJ is excluded from the current card holder exclusions. I just chatted with Amex online, who confirmed given my holdings I am eligible for the bonus offer. They will email me the chat transcript as proof of their statement.

Some questions:

1. How reliable is their chat statement later on when I (maybe) don't receive the bonus and dispute that?
2. what are other peoples' experience who were Amex DJ holders obtaining bonus points on offers on this or other Amex card - is it reliable/automatic or requires a dispute with Amex?

Automatic, never had an issue
