Reliance Bigtv — channels not getting displayed for 2 months

I have been subscribed to tamil pack. But i am not able to view any tamil channels for the past 2 months.
There was a notification saying migration will take place to tata sky but even that did not happen for me.
Every time i call the customer care they give me new timelines saying issue will be resolved. Initially i was promised the channels will be resolved in december. Then i was promised a date as jan 14th. Now they give me another deadline as january 26th.
They are not ready to send a message or mail saying there is a technical issue and the issue will be resolved by a particular date.
It is really frustrating when i get a response from customer care saying “u have to wait sir i can’t give a confirmed date when the issue will be resolved”.
