How often do you have "missing miles"?
Is any program/partner better or worse than others?
I recently had a problem with a GMAC insurance quote not posting to my HHonors account. After getting nowhere with GMAC, the HHonors rep comp'ed me the 1,000 points which was kind of her... but that's not how it's supposed to work.
I'd be interested to hear other people's experiences, good and bad.
