Since that would again put funds in escrow, it means that even if he is unwilling to release the funds to you, at least you have a shot at resolving the issue through a mediator of LBC. But this will only work if he still has an active advertisement running, and that he has at least that amount of funds in his account.
Otherwise, your chances of recovering your funds are slim. Cash deposits aren't easily refunded or reversed by banks, when compared to debit card payments or transfers.
That's true. But I don't think that's the main problem here. Main problem is that OP was apparently lured into cancelling the escrow process. If he didn't do that, then he would still be able to dispute the transaction even if the seller goes rogue.
