Amazon India — omron compressor nebulizer ne-c803/ product is not working

Sir,
I've bought omron compressor nebulizer ne-c803 on 13th feb 2017. But unfortunately we didn't unbox it till may month, because we were busy in our child's open heart surgery. When we unboxed it & used less than a week. Fumes are not at all coming just sound is coming. Now my child is suffering from severe congestion moreover he is an operated child we should take care of him more, but this nebulizer is not working. Kindly change this one with a better model, we are ready to pay more but need the best product. We've bought many products in your site but this one is disappointing us. Kindly do the favor.
Thank you,
A. Saranya.
