Tata Sky — poor service and obstructing the service

My tata sky customer ID is [protected]. I am a premier customer to them. I have one main connection added with three secondary connections. One of my secondary set top box got spoiled. I gave a complaint on[protected] and they gave a message that they will be attending the same on 5-5-2015. On repeated requests, the service person came on 2-5-2015 without any preparation and took back the set top box. On 3-5-2015, the service person replaced the set top box and went away. I received a call regarding digcomp number and on giving the number, the secondary set top box newly installed did not work and my primary connection also got disrupted with a message that there is mismatch between set top box and digicard. I made frantic calls and spent around 30 rupees on phone calls. The tata sky executives did not recieve my calls and they cooly informed that it will take 48 hours to attend the problem. This is the quality of service. For these two days, not only i have been robbed of watching tv, but also, eaten away my subscription charges without any authority. This is nothing but day light robbery. The loacal service people, did not even lift the phone or on lifting disconnected. there is no right for tata sky to treat customers in such a disrespectful manner.
