I had a nice letter from my leccy supplier today  

  Last month they very kindly gave me a month's money back for being such a loyal customer.
This month they're proposing to increase my charges by 
37%  
Oh no you don't, matey!  I've told them that if they want that kind of increase they'll have to find a new kind of customer because I'm off  

They've agreed  

  No increase in my bills at all now
