A couple of days ago I answered a call from a UK mobile number (I'm in the UK), and it was some sort of financial planning company asking about my investments, clearly about to try to sell me something. I wasn't in the mood, and did what I often do which is to ask him to hold for a moment, and I muted my end and just continued with what I was doing. After a couple of minutes he started calling my name to see if I was still there. I answered and said yes, but that I'm busy, and can't speak and please don't remove me from the list. He started swearing at me repeatedly, a lot, and then hung up. I then received a couple more calls from mobile numbers I don't know, and I didn't answer them. Today I've had more calls, all from diff mob numbers, and just now I answered one, and I could hear it was the same person... he started to say my name, it was definitely him, and I just hung up and blocked. Then I received another mob number calling. How can I stop this or what should I do? I don't want to speak to him and ask him to stop calling as he was being v rude and abusive after I kept him waiting. I guess I shouldn't have messed with him and should have just said no thank you in the first place, but I didn't. Any ideas? Or shall I just ignore all mobile numbers I don't know, and eventually he'll stop trying?
