They kept leaving me voice messages (from a recorded message) asking me to give them a call back. When I did, Customer service type of individuals answer the call saying they are from HMRC!! When I question them to make sure if they are from HMRC, One of them shouted at me saying when I didn’t believe him! He said to me “I work for HMRC and you are telling me that I don’t?!!!”, And then he hang up. I then contacted HMRC from their customer crevice numbers and they confirmed it’s the scam number!
