Good idea
My mum once wrote to Kinder egg complaining about the crapness of there latest toys, They sent her a jiffy containing about 10 toys and an apology stating due to EU rules they have to be careful about putting small parts in the eggs.

Me and a mate at work were bored one day so we emailed every company we could think of with complaints
We got a variety of cvouchers and things but probably the most impressive was from Tyrells, a huge box full of a variety of their crisps.

Win.

A mate of mine once got a stone chip in his windscreen, he phoned all the "How am i driving" numbers and complained the lorry had flicked up the stone, he got it repaired for free.

It really is amazing what you get if you complain
A guy i knew got all his food free at mcdonalds, kfc, burger king etc because he knew precisely the health and safety laws regarding the legal serving temperature of food and what not.

It was a joy to see him in action.
