Oh man, this happend so many times, and i think, thats one reason why crypto is not yet ready for mainstream !
Reverse transaction or edit message: No, i´m sorry, that would break crypto.
BUT BUT, if that was to an exchange, you should discuss that with them, for example, if it was to Poloniex, then you should open a ticket with them, because then it was just about not beeing able to direct the transaction to your account with them. They will help you.
