Error when paying for sub

[Sentaryuu]

Yes of course she is logged into the right service account. She only has 1 Square Enix ID. I only have 1 and everything worked just fine with me.

We have contacted SE through email already and they just said she'd have to wait 24 hrs, which I thought is what we did, but it still didn't work with a brand new gift card. I don't know how we're supposed to know when the 24hrs even passed. She first got an email around 3:30am yesterday saying the payment was cancelled so we thought we'd go by that if 24hrs passed or not, but nope, didn't work.

We just have no idea what to do. And really I'm not sure how much help SE can even be. They can't even tell you why a card was rejected in the first place.
