Amazon India — I'm complaining about videocon d2h booked on 14/09/2017

I booked a videocon d2h hd digital set top box with a offer of 1 month super gold hd free for rs 1720/-. However after installation of the settop box on 17/09/2017 by videocon guys i could only find rs99/- flexi pack on my tv which is a minimum plan on videocon d2h. Also it is valid till 09/10/2017 which is not even 1 month as offered by amazon.
When i questioed the videocon guys about the same he answered that you dont have sufficient balance hence you get rs 99/- flexi pack that to till 09/10/2017.
When i tried to contact the customer care of both amazon and videocon both are either busy or not available.
