Vodafone — unfair data charges and no data alert on existing plan exhaustion

I've been charged 499.99 rs for data usage, i had a 5gb plan but i got no alert when it exhausted, i used some data in mid of 11:30pm to 12:30am in this interval vodafone charged me 499 rs for data usage unfairly,

I got all alerts after 1 am. This is really cheating on your customers. I want my money back.

This is not my mistake, it's problem from vodafone's end, i want my refund of 499. No one is mad who will use data without a data plan.

I've tried to contact many times on customer care but they sometimes said data alert was sent on time some says it wasn't. I dont care what they say i just want my waiver on my unbilled amount.

I closed my data pack before 12:30 and i got all alerts after 1 am. After i was not using data it was totally worthless to send delayed alerts.
