Tata Sky — Set top box with hd

[protected] is my subscriber id
i kept on telling tata sky customer care center and had huge arguement but atlast nothing worked good for me.
paid Whole year plan of rs 7500 plus2530 plus 2530 as we have three connections
one primary and two secondary.
after 10 months they started telling we have cut money as per month charges and not annual charges.
monthly charges are rs 240 and annually comes to rs 190
so my service is closed since three moths.
i want justice.
last eight years i am customer of tatasky.
there is no need to tell call tatasky after subscribing in july 2015 that we want yearly annual package or monthly pay.
that was the issue, but no response came.
