Hathway — Frequent disconnection of network

Since last 2 years I'm registering complaints of poor network and frequent disconnection. But nobody attending the same. Nowadays they have started chatting system to register complaints which is worst ever. Because we couldn't express indepth the issue. Moreover, the engineers visits to check the router and modem are non technical and unqualified, because they used to say that our duty is to check wiring and replace the modem. The company, who introduced internet to us, now in a worst rank due to their poor service and non cooperation.
