Vodafone India — bill related issue

Address:

201301

I have postpaid number of vodafone and every month i used to recharge with 299 tarif and they provide me 20GB data per month.

But they send me bill with the mail that i used 20GB per month and also 25 GB extra and for extra usage of 25GB they are charging 500 extra of my bill.

I checked in my phone that data usage of month it is 19 GB. And i asked them to provide me per day data of month.

Could you please provide me the daily data usage records for this month so that i can cross check with my phone details. Because i have checked the same in my phone setting and the value have big differences. I get free 20 Gb data and as per your record i have used extra 25 data.
Please provide me per day data usage. I will cross check this and then i will pay my bill.
If I didn’t get your any kind of response from your service i will contact consumer forum with the records i have.

Thanks,
Anamika Talukdar
