This number has called me a number of times. The best way of dealing with these scammers, should you decide to answer, is to say nothing. If it’s a genuine call they will say “hello are you there” or your name. Scammers hang up after 3 or 4 seconds of silence from me. I currently receive three or four scam calls a day. Blocking the number doesn’t work on my new iPhone.

I answered, but didn't say hello as it wasn't a number I recognised, they just hung up
