I get regular calls from 0489 918 XXX numbers - thankfully my phone flags them as potential spam so I don't answer. I block the number but usually get a call from another similar number the next day. I know my mobile has been leaked in 2 confirmed data breaches, so I assume they have got my number and now I'm on their call list. Very annoying!!

Regular calls from this number, though the last 3 digits change, they don't leave a message, obviously spam.

No message left so I assume it’s spam.
