I have been scammed 6 months ago
Now someone is calling me from BTC REFUND DEPARTMENT
hi said that I have under my name the bitcoins that o have been scammed but the way to take this amount is to synchronise my wallet with the address that the amount is under my name the issue is that hi is asking 10% of the amount to be added in the wallet and send the new bitcoins to blockchair and then after 15 minutes all the funds will be in my wallet

Has anyone similar experience
Is this true or is just another scammer

Thanks very much
