BTW, I lost around 5 GB on a day during the last billing cycle. Airtel showed that I've consumed 5GB more on that day than what I actually did. I contacted customer care in vain. They were like, it could be sorted only after the next bill is generated. I don't know what this has to do with the bill. So, I gave up. Smartbytes costs Rs. 299/- for 5 GB. :-/
