Hathway — Hathway customer care calls for renewal by many numbers, despite of warning them

Address:

Hathway, Thakur village, Kandivali- East

I had hathway broadband connection, which I disconnected because I didn't get the service I was expecting. When the pack got over, I started to get calls from Hathway saying to renew the pack. I said them that i have got a new broadband connection and to remove my number from the list and stop harassing me, but they wouldn't stop. They have many numbers and I blocked almost 40-50 numbers. Every time I ask them to remove my number from list and not to call me, but they never listen. I have the list of all the numbers as well. If again I receive a call from them, then I'll have to take this matter to police station. Please help to resolve the issue.
