Tata Sky — No services available for last 12 days - Registered mobile no. [protected]

For past 12 days we are not getting any signal in our TV. Best part is there is no way to contact the customer service/call centre. After repeatedly trying to connect to customer service after 4 days I finally managed to speak last week to an agent, I could hear the agent clearly and he pretended he can't hear me and disconnected the call. This is very frustrating. All I get is messages that my work order is in queue. Please do the needful to unsubscribe and refund the initial amount, I will choose a different service provider since this has happened twice in a month that there is no signal for innumerable days without any support or assurance of service to be resumed
