Nebulizer that lasted five days from dischem columbine

Bought a nebulizer at dischem columbine and the nebulizer only lasted for 5 days after that the nebulizer wouldn't go on. Took it back and was told that the nebulizer was broken by me by putting in necholuptus which is medication to steam with. I asked the lady assisting me why it doesn't state on the instructions or the store that you can't use necholuptus in the nebulizer, the lady said they will contact the supplier and get back to me and I'm still waiting till this day. No one got back to me.
