Hathway — Constant harassment through every day calls

Hathway has been calling me every single day almost thrice or more for getting a new subscription or to ask if I am continuing the previous one. I have not been using Hathway for about 7-8 months now. One person I talked to asked me to pay 498 rupees to close my process of cancellation but next month I realised that they fooled me and it was a recharge that they made me pay for. This is just stupid and really frustrating. If nothing happens after this post I’m going to the police.
