Refusing bottle. Any ideas?

My EBF little girl of 6 weeks refuses the bottle completely. I pump so I can leave her with her dad while I run some errands for example but so far we have no luck. We tried 4 different bottles and nipples and without any luck. It's not that she doesn't know how to drink from it, she doesn't even let us put the bottle in her mouth. When we manage (without force, but when she opens her mouth), she just starts crying. We have tried it in the morning and in the evening. My husband tried it with me leaving the house and so fat all without any luck. Soon she will go to daycare and it is important that she knows how to drink from a bottle. Right now we have to throw away a lot of milk as we can't keep it forever in the bottle.
Anyone faced something similar and has suggestions/ideas?
