Messenger, Whatsapp Chat+Carts

I wouldn´t even give this app 1 star. Their app is not working and I have been waiting months. There are so many bugs within their app it´s ridiculous. I have lost so much money waiting for them to fix their app. It is not working. Don´t waist your time editing all fields and forms here - because it´s simply not working. They don´even respond to some of the emails. I have never experienced this before except with one other app provider.
