The message from "Dave Plowman (News)" contains these words:
Talking of which, I've had sodding British Gas at the door /again/. I won't bore you wih why I'm never ever going back to them, but I'm going to send them a recorded devilry letter informing them that they agree to pay me a handling fee of £30 for each future visit they make.
I shall look forward to taking them to court when they utterly fail to stop their slammers pestering me.
