Hathway — Bad service, fake commitment

I am taken the wifi connection from Hathway. After that every day I am facing the network issue. No wifi is working. I am raising the complaints to customer care and the executive as well who installed the wifi. But nothing happened. every day I get the same reply will work. We are doing work from home so bcz of wifi issue we all are facing issue while working. It create the fear of job loose as well. Through this we are facing the mentally disturbed as well.
