Utter nonsense

I am sick and tired of being contacted by next busters. They don’t even know how to talk English properly. I was point blank told that they will continue contacting me and I can do nothing about it. I asked the guy do you know who your are talking to and he did not even know my name, how can you call someone and not know who your talking to. I asked where they got my details and that this is against the popia act and I was told that he does not care about popia … I mean seriously they keep calling me and I keep saying no thank you and to be bul**** by someone who does not even know who they are talking to is really nonsense!! I was called by a 041 number
