Anyone else having trouble getting Mileage Plus to acknowledge eligibility for 50K deal that ended recently? After considering the trap for as long as possible, I finally gave in and sent my application in response to their "Last Chance" email. Application was accepted immediately. When card packet arrived I called to activate, that 1st rep mentioned the 50K promotion. Today I called the same number to add a pin, but the (2nd) rep found no record of my eligibility for the 50K promotion. I'm sure hoping that once Rep #2 "sends my case to the marketing department", they'll be able to track down the application date to prove my eligibility. I'm searching through all email & trash for that original acceptance email. I did ask Rep #2 if they had a twitter account, as tweets sometimes get response faster than waiting for a determination letter to arrive by snail mail, but she said no. Should I search for a Mileage Plus twitter account, or Chase Bank, or Visa. Such a convoluted web, is our banking system. Thanks for any suggestions or similar experiences.
