Dodgy scammers

Recognised as SPAM. WAs not answered and now BLOCKED

Returned call to recorded message that number is unavailable so pretty much an unsolicited call so have blocked.

Hung up. Probably checking to see if it is a genuine number so they can use it to spoof others. Already had calls from people claiming that they had received calls from my number.
