Must be terminated

Yhooo such a K**k service to the poor. My wifi was installed on the 8th Jan and it only worked 7 days. They don't respond back on their watsup,which is supposed to be open 24/7.i was promised a call from the tech 2 weeks ago.their installers don't know s*** what they are doing. Tried to contact back the installer with no luck. Just want to know if they are legit? The CEO just collects the subscription money and forgets about after that.
