Can be pushy these buggers:
But one couple became so frustrated at a salesman\’s refusal to leave their house after two hours that they called the police.
The trader was demanding a deposit for the £31,000 he quoted to replace their windows.
The couple, who have two young children, repeatedly asked him to leave before calling the police and handing him the phone so that a police officer could tell him to go.
Now all we need is a line to call to deal with the Jehovah\’s Witnesseses and the Mormon missionaries.
Can I suggest 666?
