Tata Sky — Tata sky annual subscription for only 6 months???

​

I had started off with grand sports package on 20 july 2015 which was valid until 18 july 2016.

However we cannot view channels now as of june 2016 and says we need to subscribe. ​

Question 1: why is the subscription cut early?

On ju​ne 29, i made a recharge payment of rs. 4700 to renew the subscription​ which was successful.. However, it mentions validity only january 2017. ​

​question 2: ​​this is an annual subscription amount then why such discrepancies?

This is a frustrating experience for a customer who pays his bills on time and does not receive due credit. I am hoping to receive your earliest response.​​​
