Ginger and Bear review for Sami B2B Lock,Password Protect

It's a wonder how this app got so many positive ratings. I had to uninstall the app, and I asked helpdesk if there is any codes to uninstall before deleting the app. She said no, and asked me to go ahead to delete the app. I later found remnant liquid codes. Approached helpdesk for clarification. Reaction I got was, "oh just go ahead to delete the liquid file too". Such casual attitude in answering customer queries. What if I am not tech savvy? Is there any other files or code in other files that need deleting? With such careless attitude, it might be good to think twice about this app.
