First… Their EDGE network simply does not work on my phone. It is not working at my place. I have traveled locally a bit and it does not work at all anywhere I went. I have pinged them a couple of times, they continue to say that they are looking into it.
Update: Working now!
Second… Their Smartbytes page has not been showing ANY information for my account for a couple of days now. Without it, it is hard for me to keep an eye on my usage. I do not want to get FUPed this month like I got last month.
Update: I have been told that Airtel Smartbytes is not supposed to show the usage at all. In fact, I was told that it is impossible for this section to show the account usage. Freaks.
