A sizable bonus for spending $5,000/3 months on my Delta SkyMiles Business Platinum Card never posted upon satisfying the threshold. Phoned immediately and a rep verified I qualified and stated I would receive during next month's cycle.
Bonus miles didn't post (again) and after speaking with multiple agents, a supervisor, online chat and retention (contemplated cancelling all AX accounts and pulling cash from AX Bank), was told I didn't qualify and no bonus miles would be awarded.
I was fuming and resolved to pursue via other means, but decided to Tweet @AskAmex. The Amex Angel researched and within 2 hours, resolved the issue and apologized for the inconvenience. ABSOLUTELY amazed and expectations exceeded with her empathy, professionalism and determination to resolve a tough issue (that I'm sure required senior approval).
Thank you American Express!
