Airtel — recharge amount not reflected still getting error code 6`

Address:

NO 68 3RD MAIN ROAD, GANAPATHI NAGAR, ATTUR, Kanchipuram, Tamil Nadu, 603101

We have recharged Airtel digital tv 12th April customer id-[protected]
reg mobile no-[protected]

In my account, we have around 400rs but still, on TV it is showing due to insufficient balance.

We called customer care more than 10 times, but no one can't able to fix this issue. Resolve it asap.
And also while checking in menu it is showing 200 rs instead of 400.
