My Tata sky Subscriber ID : [protected]. I have this subscription last 5 years. Often called from Tata-sky side and asked new Channel to activation. but i always told no need any additional channel apart from my pack. But last 06/10/2015 morning in my office peak time they called and ask to add 'Vedic Maths' channel. But i told 'no need to any channel'. But they forced me, as it is free for 90 days after 90days if like you can continue with pay, otherwise you may remove that channel. So i accepted to this channel for free. But they charged from that day onward as Rs.6. This information i came to know after 1week, while i got phone msg as you monthly subcribtion amount is Rs. 355. so i shocked, because my subscription amount is Rs.139 only. then 13/10/2015 i called customer care and complaint their cheating. so they removed it 14/10/2015. but they told as they wont return to my money of Rs.54 to my account after i called many times. So please take proper action on Tata sky particular department as doing this kind cheating by lot of poor people. Money is not matter. but uneducated people are, now-a -days cheated by this indirect detection from their account
