wizzo, I've seen the opposite happen too... sponsor tracking wrong, and ibill saving the day
when you use a third party processing, it's always almost 100% fool proof... unless BOTH the sponsor and say IBILL decides to shave AT THE SAME TIME... which is really doubtful hehe
Where you don't know is when all is done sponsorside like ars or CEN or CE... I think these do their own cc processing, at least they don't use any of the big third party..
then, you don't know for sure, but you gotta say if they do, they don't do it too much since they've been here forever now ... they must do something right!
