Sad to hear,but not unexpected.
your doing the right thing to make a differance. the only way I found to combat these ignorants in the past was to show them how much money they are wasting in dollars and cents. Then I supose one could annonomously advetise the fact that a refrigerant manufacturer was suppling the ozone if the cost was not a deterant. In saying al that I personally have seen no proof what so ever of ozone depletion from the scaremungers - it could simply be a natural cycle of global warming.
