Hello Experts,
I purchased the Manage Sale Promotions in Odoo App by Emipro Technologies Pvt. Ltd from the App community. I tried installing the App on Odoo 10 community edition but it ends with a "MODEL NOT FOUND ERROR". All efforts to contact Emipro Technologies Pvt. Ltd has proved abortive as they are not responding to my mails. Is there a way of escalating issues like this? so that i can get value from my purchase?. This is the link to the App.
