My friend mistakenly transfer money to a wrong account while trying to send money to his suppliers last November. Fortunately for him, he was able to get the contact of the account holder but not before the guy has withdrawn substantial part of the money. After realising his mistake, my friend contacted his bank and his bank in turn contacted the "beneficiary in error's" bank. A lien was placed on the the recipent's account. My friend contacted the guy (recipient ) and he promised to fund his own account to pay off my friend his money. the withdraw substantial part of the money the very day it was mistakenly transferred to him). And this guy true to his promise fund his account to the tune of the amount my friend sent to him in error, and confirm this to my friend. The problem now is this guy's bank refuses to reverse this money to my friend even when my friend's bank said they have contacted the guy's bank to reverse the money. my friend even beg the guy to go to his bank to write them that the money should be reversed which the guy did (this guy does not have access to this money as since a complaint of error transfer was made on his account, his bank has removed the remaining amount in his account and his balance was in the negative till he fund his account to the amount wrongfully credited to him). this guy's account is in positive now but his bank has not reversed the money to my friend 2 weeks after the guy fully fund his account. Since November my friends business is down because he can't get goods from his suppliers and his money is hanging in banking bureaucracy. please house, what steps can he take to have his money reversed to him?
