Good luck. I started calling this summer to try and run down the flex elite miles. I received the same story...but, I did ask Chase to re-send the miles. After many emails and phone calls..I think we caught up on 2000 of the ones that didn't post. As of today, I'm still missing 1000. Other miles have posted(I think) and so I'll see what happens when my most recent miles come on board. If they are on top of things, I should receive 2000 more with this statement.

It's interesting that my Sept. 9 statement did show flex miles on the page....but not Aug. and not the Oct. 8 statement. So, they are making it hard to really keep track of what is going on. I hope they go back to Chase keeping track very soon.
