Tata Sky Broadband — internet down almost everyday. customer support is rude and non-cooperative

My internet connection is almost everyday down for few hours. Today it is off since 2pm in the afternoon and now i am logging this complaint at 9pm. I have 3 month package for which i pay rs. 4, 500/-. I received sms of service being down after 2 hours it actually went down. I have more than 5 days of sms saying there is an issue with the internet in past 30 days. When i called customer support and asked to lodge a complaint and disconnect the connection so we can move to a better internet connection, the customer support person denied saying he cannot do so. When i asked to transfer the call to a supervisor, he initially denied saying there is no one on the floor. Upon insisting he finally routed the call to someone named ranjeet baliga. While speaking to this person, he too denied to lodge a complain and arrogantly says - “email karo, revert ayega”.
This is the kind of illiterate, uneducated people tata sky have on job talking to customer. When we asked for compensation, he said i am eligible for only rs. 250/- for the latest 5 days internet was down out of rs. 4, 500/- i pay for total 3 months. That too i had to ask him one by one for reason for internet down for these latest 5 days, forget about rest of the past 30 days. He could not give a breakup of amount month-wise!! He denied to give confirmation on the conversation and request to lodge a complaint over an email by saying - “email karo, revert ayega! “. He also said - “prepaid hai, refundnahi milega.”

I lost entire day productivity because of internet down, i have a 50mbps internet connection at home for a reason, not just to surf internet, my job requires a high speed internet and i pay a good amount for it. Since these issues, even if the internet is present, it rarely has goes above 20mbps.

We wish to disconnect this internet connection and refund if money for the rest of month out of 3 months paid in whole.
