Ric! You are a bad man.
That scammer is doing his best to earn a dis-honest living. You take up all of his time and give him nothing.
You have set the benchmark, 27mins. I have watched a friend of mine do similar. I never timed it. I never get those calls myself.
Did he give you any abuse like some new words?
Well done Ric. As he wastes time with you he has less for real victims.
Cheers
