Difference in Validity for 2g/3g Data

[Jignesh]

So, I have currently RC128 pack active which gives 1GB 2G/3G data valid for 28 days in AP CIRCLE.
I recharged on 26th of February
While checking 2G/3G balance in *126*6# : This actually shows Data balance expiration date as 26th March 2014 as shown in Screenshot

While checking 2G/3G balance in *122*122#: This actually shows my main balance and Data balance expiration date as 25th March 2014 as shown in Screenshot

The data balance also is different 😀

CDVOL thing is the original expiry date we get it by dialling *133# here in bangalore then selecting 1 and then 3 for data
