TV programming error

In panaji, goa they have made using set top boxes compulsory for cable TV subscribers, yet no solution is provided for the problems faced. Many of the more popular local channels like Prudent media, HCN, Goa365 and others like Life OK, sony are not available among the many channels in the list now, due to some change by an unknown person or company. Till 8 March 2016, the channels could be watched, now on 12 March 2016, the channels have disappeared without a notice.
This is extremely inconvenient for senior citizens, for whom watching TV is the main source of entertainment, especially after a hard day at work and are wasting their time searching for their favorite channel. Any suggestion to solve the problem quickly will be appreciated
