I just think they are absolutely useless at EY for crediting partner miles. I am still waiting for partner miles to past from trips I took in January. They first claimed my business class tickets didn't qualify for partner crediting even though there were a higher class than other business class fares that did credit. After 3+ months they told me I was right my tickets did qualify for credit and that they would credit the miles.
As of a month ago nothing had yet credited. I emailed them mid-June and JUST received a respond today, a full month later, that they are still working on it.
I also used a triple-mile promotion EY had for staying at the Atlantis. My stay was back in February, and only 1x the miles has posted, not the 3x promotion. I have been trying to deals with that with no luck. Atlantis keeps telling me they forwarded the miles to EY.
This really is a complete joke. Having to wait 6+ months to get mileage credits and taking a full month to respond to an email is insane.
