I am using tata sky from long time . last year I have opted from annual Dhamaal Kids that was over on 9th sep 2018. On 10th Sep I got a call from tata sky and asked from renewing on offer same pack for two years on 4680/-+ 1925/- for one year HD. I have paid total 6605/-. Now the associate said it was a mistake and not able to activate for 2 years. they are asking for another 1600/- Rupees.
