TATA Sky - It will promise almost everything to acquire you as a customer and then forget.
After sales services are as pathetic as with every product of TATA brand.
Customer care executives are not well trained and they will call you only to provide details of a new offer and will automatically upgrade that in your package. Once upgraded you can cancel the package till the next payment cycle.
Once your package is less than 100/-, customer care executives will start giving calls and SMSes which are usually annoying.
Will not recommend TATA Sky to anyone.
