Thank you for the reply and sorry that my request wasn't clear. I don't have a plugin license key. We canceled the plugin shortly after purchasing since it did not provide what we needed.
I'm trying to add a screenshot to verify when I hover over my icon in the upper right that it does not show a key. It will not allow me add a screenshot. The list of options are:
Add-ons licenses
Edit profile
Change profile avatar
Invoices generator
EOQ calculator
Please, I'm looking for a way to contact the billing department for a refund without having a license key to do so.
