They have deducted 2 days subscription in single day when I was down grade my pack.
They are not giving subscriber retaintion offer when you was deactivated from couple of the months.
There is no discounted pack in TS for economy users like nonstop pack in dish d2h and UDP pack airtel and discount ncf like SD.
Not quickly added new channels. Lots of things
TataSky no doubt..... I'm a ADTV user but since TRAI changed the tariff of dth industry there isn't much difference between TS or Airtel in terms of cost. Both charge the same now. Although TS on-site services are still a bit higher than Airtel. But with DTH you don't always need a technician visit unlike local cable services.
