Airtel
Invalid recharge vouche

This is dr jameer kamate,

i had taken a recharge voucher of rs-30 for my airtel card, but when i typed the pin as stated in the card, it said that the recharge pin is invalid, i tried it couple of times but all was in vain.

the pin no was 6850 1598 0642 44.

i am really sorry to say that airtel services are becoming bad to worst
