I've been trying for DAYS to get someone at Delta to explain to me why I have not gotten the additional platinum choice benefit like so many others have here. I received a canned (and incorrect) response to my initial inquiry, but NOTHING in response to my follow-up, and NOTHING in response to my second follow-up. It has been 3 days and not a peep from Delta support.

Should I call the DM line? Why is Delta support ignoring emails from a Diamond Medallion? Do I have any recourse? Is there someone on this forum who could look up my ticket and tell me what's going on?
