Can I get my money back in case I send it to the wrong person?
That depends on a number of things including the service provider that you chose to work with. There are cases where the wrong recipient gets to withdraw the money making it hard to reverse. Sending money to the wrong person is however unlikely because most of the money transfer services force you to confirm the entered details. That means, if you send money to the wrong recipient then it is not the fault of your transfer agency.
