Wow, just checked and saw that your post has 110 (111 with this one) replies and just under 3,000 views. So many people seem to care and so many have sent in donations to help. Sadly it sounds like your fish are still in need of a miracle to survive though.
What if we all send an email to the york company with the details of what you have gone through? Could you put up a few sample letters that people could cut and paste into an email and send? I would think the more negative responses this company receives the sooner they will wake up to your situation and see how they owe you a whole new furnace system.
Also, is there any fundraisers going on yet? If so, I would be interested in purchasing an item or ticket or whatever you have going to help.
Let us know.
