Hathway Cable & Datacom — fake bill generated for my discontinued services and threat calls

Address:	110092
Website:	hathway

Myself aditya singh, discontinued my hathway broadband service ([protected])two years ago, which was prepaid. But now suddenly they are making various calls and threatening me to pay amount Rs2190 otherwise they would be taking legal actions against me and even giving messages on mobile to pay amount immediately to avoid charges. So now what to do, no response from customer care. I also checked the number from where they called and its showing spam.
