[Resolved]  Hathway Cable & Datacom — fraud company

I have discontinued with hathway services 6 months back. I also returned the modem 2 months back and they gave me NOC.
But now they keep calling me everyday and when i asked them that i am not interested so stop calling me. The guy on the phone said you have some outstanding amount due. And we will stop calling when you will pay us money.
I told him that i have my NOC and no amount was pending and i will file a complaint if you will call again. And the guy told me you can do whatever you want i will still call.
This is the number from which he was calling- [protected]
