I recharged my phone today afternoon, for rs 10.. My balance was zero. It was just to sent a message. Recharging was done with Google pay, but amount reduced was 1000 rs. I called customer care executive. Asked for refund but said it is not possible.
I was frustrated actually. So planning to port to airtel.
