When I tried to convert my Blue Rewards to Blue Cash, the cs rep. from India told me there is no formal way to convert. That I had to apply for the Blue Cash than cancel my Blue Rewards.

Knowing different, I made repeated calls and finally got a stateside Amex rep. who knew exactly what I wanted and did the conversion.

Recently I called to upgrade my Amex Green to Amex Platinum and once again a cs rep from India answered. This time the rep. seemed to know what I wanted and told me that the conversion was not a problem.

This is the first time that I actually had gotten a India based rep. that was able to help me.
