Airtel — twice recharged on same number

Address: Hyderabad, Andhra Pradesh, 500033

Hi recharged twice on same number for 1699
And airtel wants to keep the money, it's sad once a genuine company with good network, has network issues and is stooping to this level that they say u have done it so we are not responsible and want to keep the money.
