Ratings and reviews

The app does fail to open from 8pm to 10pm and sometimes 10:30pm which is very annoying and infuriating. so I'm rating the App just two stars.

The app is now working perfectly but the call tariff is high. not different from normal call rate.

please I need you to work on making it accessible, not only I must be online or when i make use of the app that someone can contact me through the app. Also I need the ability to send SMS through the app and can still continue call conversation while checking through my phone directory.
