Airtel Postpaid Connection
Excess amount deducted from Credit card

I had 2 psotpaid connection. And I had given my postpaid no. to conversion to prepaid connection. So I cleared my bill and un billed usage. After clearing all my dues the cheque was under clearing process. Whereas, the same amount was debited to my credit card through ECS.

Because of which the second amount which was debited to my credit card was refundable to me. But they also deducted the rent for the next month. so, After clearing all the dues, unnecessarily I have to pay Monthly rental for that number for 2 postpaid connection.

I want my money back. Kindly look into the matter.
