It's a classic. They play on the fact they have a legel, verbal contract. Just go Liam Neeson on them. I will find you and I will kill you. They generally go bother someone else at that point.Any one else had a firm from Liverpool thanking them for supporting the local Police by taking out a quarter page advert in some magazine? I've had it two years running, they ring up for £150, and sound very plausible. I can imagine some secretarys in large firms just paying up.
