Airtel — recharge error reg

Address:

Chennai, Tamil Nadu

Respected sir/ madam,
We are airtel family, on nov 3' 2017 i recharged for rs. 399 unlimited free calls and 1gb/day valid for 70 days. On nov 11' 2017 instead of recharging my husband's number i recharged my own number for rs. 448 then after a second i called airtel customer care and i said i recharged week before but mistake had happen kindly recharge my husband's account with rs. 449 or refund it. I lost almost rs.900 for that they simply said we cant do anything from our side and i requested them to do this favour that i am asking my own amount and i am not asking any offer from you but no response from them. No humanity
