RCM Business Official App is not a good application for shopping online grocery or daily need thing. There are not available every famous brand of grocery. That is the main concept of the application. Layout and design also not maked so attractive and good looking.I have joined recently with RCM so I downloaded this App. It is very slow loading. I dissapointed with this app. Feature and function also not good. Adhar link is mandotary to use this App. This application not usefull for me. Useless app.
