Tata Sky — No service even after repeated complaint

Address:

Bangalore, Karnataka

I have two connections. The subscription ID-[protected], Since April 2015 both set top box is not getting signal & and are non functional. Menu pages appear but no channel signal. Customer care is not responding to my complaint. Online complaints gets closed without attending to the fault. For past one week, the help line nos are non functional. Very bad experience and poor support. Dont know what to do and whom to approach.
