Vodafone — Overcharged for data usage

Address:

Interaction no.[protected] with vodafone.
I have been charged approximately rs. 335 exclusive of taxes, for internet usage.

My total free bandwidth is 500mb as per vodafone communications. I have also sent mails to vodafone with screenshots of messages received from vodafone itself in which it is mentioned that my current internet available limit is is 500mb and i have also checked on vodafone ussd code *111*5*1# and i have proof of message received from vodafone dated 28-06-16 which clearly mentions that i have 249.97mb data left. But after this they have charged me for 82 mb of excess data usage.
This is totally harassment from vodafone side and this has happened with me second time.
Please find the screenshots of the messages from vodafone for dree data limit.
