Sometimes the online payment for recharge just does not work and then you are left twiddling your thumb what to do next. Call centre will be as unhelpful as they are in India. 24-48 hous will be refund time. So keep fretting and fuming till then. I am experiencing it right now. The money just disappears even when you get a mail confirming the payment. bad back end work on their part. And you dont get any information till the time you call up and blast them for this shoddy service
