So it seems really daft on reflection, but I accidentally gave my number to a little gimp thinking I would use him as a business contact (as we started talking about him providing a service to the company I work for- to me this is networking)and we had some coffee and a chat.
Now he calls me almost everyday (for the past 3 weeks) I only ever answered the calls when I thought he was normal, but I have entirely ignored the last 20 or so calls.
Then he spotted me one day and approached me declaring (very loudly in a nice, civilised cafe) that he had been calling and calling and I never answer. Wanting to cool down the situation (which could have been very humiliating) I said "Oh well I think my phone is broken" and sort of brushed him off until he went and sat far away. I exited swiftly and didn't talk to him again. But he didn't get the hint, he kept calling. Thing is- I never, ever answer the phone.
In this culture what's the best thing to do?
What would be a sure fire way of getting rid of this little creep?
