Vodafone — Billing cycle date changed without prior notice

Address:

New Delhi, Delhi

Last month I had converted my No.-[protected] from prepaid to postpaid. The procedure had been completed on the 10th last month.I was the of the view that since the process has been completed on the 10th so my 1st bill would be generated on the 10th next month.But Vodafone without any prior notice changed my billing date from 10th to 6th.I'm using a plan where I get 1GB 3G data and after that unlimited 2G data.Since I was of the view that my next billing cycle would start on 10th August so I thought that my new 3G data would be credited to my account on the 10th of August.But since Vodafone changed my billing cycle from 10th to 6th without notifying me or without my prior permission my 3G data was credited to my account on the 6th.Since I was not aware that new 3G data has been credited to my account I kept on using the data.It was until yesterday that I got to know that I have consumed 80% of my 3G data.Now since I wasn't aware that new data has been credited to my account on the 6th of August i demand that my data be returned to me.Vodafone Appellate Authority has denied my request.Please look into this matter.
