Now, the only solution is that the sender makes a new transaction.
Take note that unless you completely trust the sender, you should never accept an unconfirmed transaction. There is no guarantee that an unconfirmed transaction will be finally confirmed.
Yess, exactly. I saw it, but the 360 sec limit wouldn't let me respond it. I'll send all in the same post now.
hosseinimr93 and nc50lc - happened what they said.
child pays for parent, indeed I don't have this option, but I thank Abdussamad anyway, thank you very much for your time and attention.
hosseinimr93, It's a person that I buy regularly from him, I guess and hope we'll fix it, I'm already talking to him. I always send the money before he sets the transactions, Our relation makes it easier to me trusting him, than expecting him do trust me.
Anyway, I'll let you know later, thanks all for the help
P.S. - any way to thumbs up the replies?
