Donna,
I had a similar experience as well... My first order was perfect and I was very happy! Then on my second order I had ordered several fish with the express instructions that they NOT be delivered on a certain day because I would not be home to recieve them. It happened to be Jan in Vermont, about -10F! Needless to say they shipped them overnight to arrive on the day I was gone... 3 dead fish later, I complained and complained and they never admitted any mistake, basically told me to pack them in salt and ship 'em back and the NEXT time I order I could get a credit. They also said the heat packs should have kept them warm, maybe on a 50 degree day but not when it was that cold!
Sorry for your experience
