Has anyone had problems with Virgo home improvement salesmen (UK)?

What a turd...... I have no reason to dis-believe your story. I'd bet he won't turn up. If he does, just call the old bill. Sounds like he's a sad human being to me. Did your wife give him any verbals to kick off so suddenly ? Get some of your friends around to be on the safe side as he does sound mental. Good luck.
