Consumer Redressal

I am a customer of Hathway broand since few years and for the last 3-4 days the service has been pathetic. I am working as HR recruiter in a US firm and need to cntact my clients on daily basis. In the last 3 days I have not been able to utilize my time properly owing to frequent disconnection and loss of signals of Hathway broadband. I have complained to the service centre on daily basis since last 3 days and nobody was bothered to rectify my complaint. Today one of the engineer Nikhil has come and said the issue is a major one and it would another 3 days to rectify the problem. I am facing enormous mental strain because of the frequent disconnection. Due to this disconnection I have lost business as unable to call my clients and I am at the verge of loosing the job. Who is responsible for this. I need an explanation from Hathway or compensate for the loss I have borne and agony faced due to the irresponsible behaviour of the service provided
