Trai — videocon d2h service and rules against trai

I am suscriber of videocon d2h services with consumer id no. 80451862 We have sufficient balance in our a/c & from last 5 days videocon d2h has stopped airing our preferred channels abruptly. As per their instructions, we have given list of preferred channels via online on there website for not less than 4 times since 10.04.2019 on wards but still we are unable to view our preferred channels. We have two connection of d2h one is HD and another one SD, apart from that also when we selected package for both the TV separately always same package is activated in both the TV and we are not able to see any HD channels as well not able to see any free air channels. Now when we are calling to customer care no of vediocon i.e. [protected] always showing line is busy and after the very hard effort to try more that 25-30 times once call connected and they told we don't know any thing please hold and that hold for long time and call disconnected, this happens more that 10 times. We really frustrated even this word is also very small, now i think we have only one option to change service provider if not getting any solution within couple of days. Attaching some of the images of screenshot of call to show how they treat old customers and worst word is also very small for this . Any Solution ?
