I threatened a car lease company with that when they failed to collect one for over a month..
Worked a treat, they turned up unannounced within 48 hours and didn't charge for things I thought they would - scuffed alloys etc..
Or
Sell it and if they ever do come to pick it up, claim that someone from Argos picked it up a week ago......
When we moved house they had made it very clear if we didn't complete by this date etc etc we would be charged by the day certain fees etc
They phoned us 3pm moving day to say it couldn't happen today due to some problem I pointed out they would owe me x amount of fees laid out in their contract for not completing on the agreed date
Yeah we were given the keys by 4.
