A few years ago we lost a customer whom we had been doing for years before they canned us. A letter came with the Chq saying they were canceling window cleaning.
We thought it was odd so we rang them up to see why, in case its something we did.
Well the wife said that they had been knocked and the new guys were cheaper so it would save them money, £20 bungalow, the husband thought they would try these new guys. Fair enough. Its their house so they can have whoever they like cleaning them.
A good few months later we get a call from said customer asking if we could add them back in as the "new" cleaner wasnt very good, broke the top of the gate climbing over and then decided after breaking gate if they werent in he would do fronts and still charge full price £18 i think.
We do them again now and they cant be nice enough about us :-) I think they have learnt their lesson!
