Independent TV — unable to view/see any channels from last week

Address:

OLD SANGVI, PUNE-27, Pune, Maharashtra, 411027

I have opted the Independent TV connection in March 2019 with HD channels pack. Around last month the HD channels have stopped working and from last week I am unable to see any paid channels, also whenever I am trying to contact given Independent TV customer care number it's always busy and I just can't reach to them. I had sent multiple emails for this but no reply, this is pathetic and I am not sure what else I should do to get it rectified.
