I encountered a polite but inflexible phone rep yesterday. I need 2800 miles to retain my silver status in 2010. I acutally earned enough mile if CO includes a double qualifying miles promotion for a flight to amsterdam that i flew in June. Trouble is I didn't register for this one promotion beforehand. (I did register for a similar one later in the year.) The rep was totally inflexible. I've been gold or silver elite for the last 8 years and she wouldn't recognize that. I would appreciate advice on how to escalate or otherwise handle this. Thanks much.
