Asianet Satellite Communications — not receiving subscribed channels

I had subscribed for a la carte channels (52 nos) and paid an amount of rs 960 on 1st april 2019. Even after they received the amount i found that several channels that i had paid for were not being received. I visited the asianet office at thiruvananthapuram on 2nd april and informed them of the same. I was told that the plan has not migrated and i had to pay rs 12/ for it. Nothing was done and i registerd a complaint on 3rd april which was not resolved, but the following day i received a message saying that it has been closed. As i was away from station i could not follow up the position of the channels. However on my return i again registered a complaint on 9th april. On 10th i was informed that while opting for a la carte one doesn't receive all the channels selected and that there is a limit to the channels that are received. (Nothing of this sort was mentioned in the site while selecting/accepting payment online) further i was given the contact no. Of a person who could solve the problem and my complaint ticket was abruptly closed. I contacted the person and was told that the set top box had to be changed and it would be done promptly. On a reminder today, the 12th of april, i was told that there is a shortage of set top boxes.
April 1st is april fool's day - not the entire month! What kind of service are they providing? If they do not have the channels that i selected (And paid for), then why don't they just admit it and remove those channels from their site (Which, by the way, is absolutely rubbish). I demand a solution to this - since it has been 11 days since i paid the amount and the validity of the amount is only till may 03. They seem to be following the adage "customer is king - only till he pays the amount". Thoroughly disgusted!
