Videocon D2H — distance in audio and video sync

Address:

Ahmedabad, Gujarat

Hi. I've upgraded my d2h from sd 2 hd. Since i have upgraded i am facing problem that the audio is not sync with the visual effect. I have complained so many time for the issue but till today my complaint is unsolved. During this things my remote is also not working properly. The upper part of my remote is not working as before it shows the channel list. I also complained for the same but no one is taking care. Please resolve the problem at the earliest or refund the amount paid.
