Schemes get activate on Airtel DTH 3012858726 without intimation

Hi
I am Raviraj Dhamapurkar
My Airtel DTH 3012858726

From last month Schemes get activate on my Airtel DTH ID : 3012858726 without intimation & this happened second time with me.

My rental is Rs.220 for 30 days

I got a FIRST message from airtel DTH that my pack rent is changed to Rs.235 from Rs.220, which i did not requested to them.

I got a SECOND message from airtel DTH that my pack rent is changed to Rs.290 (FOR HD PACKAGE ) from Rs.220, which i did not requested to them & i am using normal CRT TV & i dont have HD TV.

I dont require all this additional packages,but than to AIRTEL DTH are activating this additional packages without any request from my end.

My rental should be Rs.220 ONLY for 30 days and not any other rental package.
