Alibaba/Trade Assurance dispute on red light panel

Hey everyone, I need some advice about an Alibaba/Trade Assurance dispute.

I bought an AL1500 red light therapy panel from Alibaba. After receiving it, I found that there was no clear technical manual or detailed documentation showing the actual wavelengths, operating settings, or what the preset modes contain.

I contacted the seller after receiving the product and asked for these details because I want to know exactly what the panel is emitting and how to use it. The seller refused and said the settings are part of a “confidential project.”

This confidentiality issue was never discussed or mentioned before I purchased the panel. I only found out after receiving it.

So now I have a product where I can't properly verify the wavelengths or settings, and I don't have enough information to know exactly what I'm using.

I’m considering opening a Trade Assurance dispute and requesting a full refund.

For anyone who has dealt with Alibaba disputes:

• Would this qualify as “not as described”?
• Who would normally pay the return shipping?
• Can I also recover the original shipping cost to Canada?
• Should I wait for Alibaba’s instructions before returning anything?
• What evidence should I submit?

I have screenshots of the listing, order, product, documentation, and the seller’s messages refusing to provide the settings.

Any advice would be greatly appreciated.
