Videocon Industries — Stars sport hd channels not working

I have recharged my set up box with star soprts 1 hd and plan is expiring on 31 august. Still star sports 1 hd channel no 620 is not working, rest all the channels are working fine which suggests there is no weather related issue. I mailed to d2h but availed no response. Its ind vs pak match today and i missed it completely. After all efforts of troubleshooting i deleted the channel from my pack and added star sports hd channel no 648 and did a fresh recharge. To my surprise this channel is also not working.

These sports channel are recharged only for such match days and if on the very day it starts showing signal not available for that only channel then the entire plan of that channel for the month is waste for me.

Very disappointed with the service.
