Try asking My request to speak to a supervisor was steadfastly refused. In the end I rang back, got routed through to the CS team in the UK and problem solved. I also told them what had happened with the Bombay call centre... greeted with a knowing sigh.

If any of you think Amex is doing a bad job of this, write in, it's the only way you'll stop all the call centres in the US/UK from being contracted out to other markets.
