Try to inform the bank and bank manager immediately
after the wrong transaction. Money will get back to your account automatically,
if the account number you mentioned does not exists but in case the situation
is opposite, you have to take immediate action.
Unfortunately, payments to the wrong account can't
simply be reversed, so here's what you need to do for the best chance of
getting your money back.
