LBC is a scam company, Where you able to get unfreeze your account? If not we need to find the people in charge and then we can file a case agsinst those scammers.
Before you do that why not post your proof on your own thread of your own accusation against LocalBitcoin, OP's case is very unusual why take two years before you post it here, if his alibi is he is not aware of this forum then post a platform where he first posts about his issues, there's no proof or screenshots of transactions either make both of your complaint hearsay.
They are not scam but the its users are prone to scam especially those payment method that can be reversed worst to those who aren't. Example to OP's post, Skrill transaction cannot be reversed, but the other person reported that the money sent in skrill was reversed, but still LBC required the op to send the money back although it was 10 days already past knowing that the used payment method is known that cannot reverse the transaction.
4. Sending money
4.1. We strongly advise you to only send money to people you know. Once the funds have been debited from your Payment Method, you will not be able to cancel or reverse the transaction.
Although this is just OP's post without any given proof but who would waste time posting here if it doesn't happen to them especially complaining to a company not to an individual.
