The last one I had was from a very Indian voice, giving me the same spiel that scouse got. I told them to go away, but used two different words.
It was 11:30pm, and it woke me.

Sometimes I just talk gibberish until they put the phone down.
I sometimes wish that I had a recorded message from an evangelist that I could start and leave them to listen to, at international rates.

I'm getting really tired of being cold-called on a phone that 'I' pay for.
