Videocon d2h

I have done a recharge for add on sony ten3 and it was for one month and it is not mentioned any language intl their d2h infinity app but when recharged i realise that it was a hindi channel and i need to watch world cup in english and when i called a customer care executive and said deactivate it or change it for sony ten2 which was in english but they had a very bad behaviour and said it can only be deactivated after 3 months and i can't even change the channel to english during this period. I was very disappointed that i can't understand hindi fluently and the channel was for three months and they will debit money from my account balance.
I have used other dth services before and this is the most worst experience i had... They cant even change the channel language though the both languages are available in the same value it is very disappointing...
