Airtel — airtel dth not providing channels of my choice

Address:

Ernakulam, Kerala, 682028

I chosen channels as per trai regulations & amount is rs.200.41. I recharged for rs 201, but they suspended my ac & stopped all channels. They wanted to recharge old rental 237.& deducted some amount from my recharged amount (No. [protected]). Now the ac is suspended when i contacted them, they least bothered to resolve issue. How can they deduct from my paid amount since old plans were "prepaid" pl instruct them to restore my connection asap as per my opted plan & to fix the next due date as and when it is restored. If by their mistake, any negative amount is reflected in my ac, pl instruct to waive off and restore the connection with my choice
