Really confused and angry about spam calls I received.
For example, recently I got a call from fm-fx, some kinda financial company asking me whether I want to make money. I am so sure that I did not sign up anything from their website so I am so confused how do they have my phone number and my name. Ten minutes ago I got a call from "Select and Switch" saying that they could free compare elec bills for me. So I asked where they got my detail. They answered "public database". I am so annoyed with this kind of calls. How could I prevent them?
Some scammers have robocall machines that cycle through every number in a range because whole country towns have noticed that everybody get the same scam calls around the same day.
