Happy Wifey review for Globo Mega Menu, Navigation

I had a terrible experience with this app, and the customer service is not very well either. When requesting help to install the app properly, they made changes that did not work at all, and published it so it was live! When I asked if they could revert the changes, they did not respond. Also, the menu did not include brand logo or cart, essential for any ecommerce store (how can you buy if there is no cart?)
