I don't know how old your account is, or how good you think EA's book keeping software is, but if you think they can track 10 years worth of successfull credit card charges for every individual account history... through all the changes of managment, ownership, leadership of UO over the years etc... I think you are being optimistic.
I'm not saying they shouldn't have a way of knowing how old each account is, since they've had a "Vet Rewards" program for many years they should have "Tracking" account age down to a science by now, but I don't think it's as easy as typing in your account name into some magic account system and counting 120 successfull charges in a list.
