Phone rang & stopped before I could pick up. No message left. I’ve been receiving dozens of these over the past 6 months. Don’t call them back. It’s a scam call where keeping you on the phone waiting pays the scammer for that time. First time I called back, they put me on hold... after a few minutes, I realised it was a scam. So I don’t pick up any calls that aren’t in my contacts anymore. If they don’t leave a message, it can’t be that important!

Recently, calls like this only ring a few times so if away from your phone you cant even answer it. No voicemail left and nofollow up SMS. I can only assume it's a scammer. If it were important, they should have left a message.
