We've had about 6 phone calls in the last week or so telling me they are from a security company and want to talk about the security of my computer blah blah blah. I'm guessing they are from India due to the accent so the opt out register is useless in this case. I've told them I have been in touch with the police and today I told them I don't have a computer (they hung up).
I've just had another call from them. What else can I do?
