Man with ethnic accent said they have tried to call me on 11 separate occasions (missed many calls from the 02 7245 prefix), did know my name, stated I have been scammed and they have been appointed to return my money, approximately $6,000 in value. Said they needed my details to make the transaction and mentioned I'd been scammed through most likely crypto but have no details of the scam. Stated I don't dabble in Crypto and I have not been scammed, called him a scammer and disconnected the call.
