Tata Sky — No signal since 16th on my multi TV connection: Subscriber ID : [protected]

I am a TATA Sky subscriber with Subscriber ID : [protected]. We have been receiving no signal since 16th of April. I have registered complaint and have multiple times chatted with online agent and called customer care too. Each time I am getting the same response that my complaint will be attended shortly. I have received SMS stating pending techinican visit but so far no one has turned up. Tried calling Nodal officer number shared for escalation but no one is picking up. I am fed up with pathetic customer service (huge delays and no resolution) giving standard response. Also I am being charged daily for the service not being rendered.
