Often a good piece of wood like a solid table top breaks cleanly and can be repaired successfully as follows.
- Buy carpenter's wood glue from any home improvement store. A common brand is Elmer's though any brand is fine.

- Apply the glue completely covering both broken raw-wood surfaces.

- Clamp the two toegther for the right bond, squeezing out excess glue

This is a good method using cheap pipe clamps.

- With a hot wet rag, wipe off excess glue, it cleans off well with warm/hot water.

- Check for alignment of the two pieces to assure a nice bump-free alignment, adjust as neccessary
- After a few days in the clamps, it's good, but since it broke once, I strongly recommend screwing two hard wood wooden rails on the bottom for increased strength.

If this is not somthing you can handle, and you do not know anyone who can do this, then as suggested, contact the factory and they will sell you another one.
