Omron Nami Cat Nebulizer Spare Part Request for Medication Chamber

I purchased the Omron Nami Cat nebulizer, and it has been working perfectly without any issues. I’ve been using it regularly until recently. Now, I’m in need of a replacement medication chamber, as the product is still under warranty. However, I haven’t been able to reach anyone to assist with this request.

I would greatly appreciate some help in obtaining this spare part. It’s frustrating not to get a response when the product is under warranty, and I hope this issue can be resolved promptly. Thank you in advance for your assistance!
