This number is Aust so I answered it but didn’t say anything. I waited but all I heard was background noise so I hung up. Quite similar to some other Aust calls which claimed I made a purchase for a certain amount which I thought was genuine since they knew my name address & email! Until the crunch came when they finally said they were from Telstra - an account we don’t have! Keep blocking the numbers but they just keep calling. 😩
