Rang me up yesterday to talk about a deal with my phone which is on contract and then today rang me about a "Security Issue" and said that "A colleague" had rang me yesterday but I could tell it was the same person, After I informed them that there are a lot of complaints online to do with that number he was using I hung up and they continued to spam call me 6 times in a row. After giving my email address yesterday I was afterwards signed up for a survey site!
