I was told during a phone call to the AAdvantage desk that someone would get back to me within 72 hours.

However, I received the e-mail with the four different offers about three weeks later.

I also chose to receive miles instead of LPs for my purchased upgrades.

However, I just checked my AAdvantage account and it appears AA converted all of my paid and complimentary 500-mile upgrades to LPs.

So I will call them tomorrow, reference the e-mail they sent me and attempt to ascertain what the heck happened.
