Really? I switched back and forth with AT&T and they didn't credit me with the entire bonus miles the 2nd time because I got some bonus miles the 1st time already (I was told).
i.e
* 1st time signing up: got 5K USAir
* switch to another phone company
* 2nd time signing up for a 10K promo: only got 5K because I already got 5K the 1st time
Has anybody else gotten this treatment?
