Trai — tata sky multi tv charges double after the new regulation

Address:

My tatasky multi tv charges have doubled from 250 rs per month to 500 rs per month and there is no information in their website about his and i wrote 3 times to [protected]@tatasky.com but not getting any reply. Before i used to 1370 rs for telugu, tamil and bengali all channels and now for half of the number of channels i am paying 1710 rs. Since i am not getting reply for tatasky, hence seeking for clarification here. Is the multi tv charges regulated by trai or tatasky. Please confirm.
