The first time I used ET Payment was with a gamestop gift card, I had 35$ on it and it had credit me the money. Now my ET balance is -35$. I tried putting in 10$ with a subway gift card but it says I owe 45$, but when I tried using the option for gamestop, It just says the total is 10$. Why is my ET being charged for the other options other then Gamestop? How do I pay off my -35$ without having to spend extra money? Is this an error?
