Videocon Industries — worst customer service from videocon d2h

I have called and selected the channel through online but they activated their base pack. When i found error in channel pricing as per trai mazhavil manorama hd is free but at first videcon charges 19, calld cs they talked in very undecent manner and they dont have any technical background also no commonsense. Dont but videcon d2h its the worst d2h service provider in india.

When trying to call cs now all time bust, mail no response. Then what to do? Going to use other service provider.
