Oh Jill, what a shame, pretty though they are. Unfortunately it does happen, I grow bulbs for a living and this year employed someone to help me with the packing. (I know the bulbs are correct at harvest, not only are they labelled,they are also marked on a planting plan and well separated, but even then two of my customers got the wrong bulbs, and I'm pretty sure it wasn't me!
My customers have been well recompensed I think (replacement bulbs and their money back), but I still feel bad about it. It doesn't make up for it.
This year I am just going to have to work more hours and do it all myself come packing and despatch time.
