Today I called my bank. The VERY polite agent told me that SE is "checking" the payment details, and they have up to 7 days to do it before rejecting the transaction. After all the attempts I've made, they told me I have 7 transactions on check. The last one expires this friday 27th. Lets hope one of those gets through. If not, I'll just try again on Saturday... Anyone has any clue on this?
