Sir,
I sent rs 448 for airtel prepaid on 2.5.2018 but amount dedcuted 2 times through my sbi crrdit card. Kindly refund the excess amount or extend the voice/data facility for another 84 days. My cell no.[protected]. First i tried on www.airtel.in for payment of rs 448 it was hanging then i tried second time so i did not realise 2 times amount of rs 448 dedcuted instead of 1 time.
