National 6x US bonus miles missing.
Last year i rented from National twice (sept,nov) as they had 6x miles bonus instead of the usual 2x mileage. Both times i only recieved the usual 2x miles. I spoke with National and they said that the bonus miles come from US air. I called usair twice. They acknowledged the missing miles, and noted my account about the missing mileage. Still no miles. I wont even bother renting from national anymore if they [us/national] can't get the mileage right. In the interm; has anyone had luck collecting the additional bonus miles? If so how?
thanks!
