Hi! Sorry to hear you're having trouble.
If you can send a copy of your save file to the email address listed under the "Technical help" section of the store page here, I can offer more specific advice, but the main things to keep in mind are that wax costs pollen and nectar to produce, and that Worker bees (the ones that by default have no hats) are the only ones that can work at production facilities.
You can also view the production screen by clicking on a Wax Assembler to see what the current production status (whether that's producing, waiting for workers, waiting for resources, or inactive because storage is full).
Hope that helps!
