Hathway — Termination of internet connection for past 2 days..and no proper response from the team

My internet connection has not been working for past 2 days, when I tried to make complaint about it I did not get proper response from them..and they were avoiding calls from my end..I tried to know if they have terminated the connection or its because of some other issues..even for that I dnt get response from them...then I tried to register my complaint about this on their website it showed like you don't have any device connected and so I was not able to register my complaint..I've even paid my bills...still I'm facing this kind of issue... I've been preparing for my exams but for past 2 days I'm sitting idle without any internet connection...it's affecting my studies alot...I need solution for this. VERY POOR SERVICE I've ever seen so far
