"I Mistakenly Transferred Money To A Frozen Bank Account, How Do I Get It Back?'

I made a transfer to a man whom I buy bulk knitting wool from, but he told me that the account have been frozen and he doesnt have any plan to go and unfreeze it cause he have gone to the bank four times they didn't unfreeze it.
Is there any way I could get my money back? cause the man have already told me that my money is gone, cause there is nothing he can do.
And the money isn't even mine, I am just a middleman for people who want to buy wool in large quantities.
Pls nairalanders is there a way I can get my money back??
