A little context: like many, i've had trouble with failed transactions lately (see /r/monerosupport). I was trying to purchase something through xmr.to->bitpay->vendor. My first 2 attempts failed (or so i thought) and the transactions on bitpay and xmr.to both expired, third attempt went through. But later I saw that the second transaction also went through.
My general question is how these expiring transactions are handled? Do the addresses they give you still exist? Or is there a way to somehow block the transaction from coming through once it expires?
It's been many days and I have not been able to get any info yet from xmr.to to see if they still have the money or if they forwarded it to bitpay.
