Hathway Cable & Datacom — hathway cable

After the change to the cable charge post trai regulations my bill increased to more than 300%. I asked my cable operator to change the channels which i do not use by month of february yet, i got the same bill by february end, which i paid and asked him to make the changes but this month again same bill came. When i asked he is threatining me and my old relatives who stay downstairs with abusive words in front of my neighbors. I told him to disconnect yet he is not discontinuing. I kept on calling the customer support of hathway multiple times, but nobody picks my phone.
