hi, friends i have activated the a la carte pack few months back on my airtel hd box.the problem is that due to my ignorance i have activated some channels thru sms,by myself .i have since deactivated those channels but my daily burn rate amounts to about rs.200 p/m even though my selected channels amount to less than 150.so how do i reset my pack to the base pack and reselect my channels.thanks in advance
