Tata Sky — Without information increase in the monthly recharge value why and how come?

Address:	Pune, Maharashtra
Website:	Tatasky subscription

I am regular payment subscriber for TS since last 8 Yrs or so, in the beginning I use to pay Rs. 375/Month then it was made Rs. 575/ month, it was OK we added some channels. Surprisingly now without addition of any channel or changing the channel package my subscription value has gone to Rs. 843/month, how come is this increase with out any sort of information? Please, can one explain to me? I want to continue with my Metro Package with addition of Pogo, Baby tv, Disney Junior, Cartoon network, and Color Marathi if it is not included in Metro Package. I would be obliged to receive your earliest up date subscription amount per month so that can immediately recharge the required amount by means of recharge facilities available to me, as the recharge date is due on 8th Feb 2016. WAITING FOR YOUR QUICK REPLY TO AVOID INCONVENIENCE.
