Vodafone India — fraudulent international roaming charges

Address:

560066

During my recent international visit to japan, i requested vodafone india to activate iroamfree pack where i had to pay activation charges of rs 149 (Approx) and after that only if i do anyone of the following 4 activities i was supposed to incur the charges of 500 rs for that day:
1. Make a call
2. Receive a call
3. Send a message
4. Use internet data
During my stay in japan i did not use any of these services and i was only using the wi-fi for my day to day activities. I would like to repeat here that not even once i enabled vodafone internet service neither made/received any call nor i sent a sms and i have not used even 0.1kb of data still vodafone has charged me a whooping rs7107.14 by claiming that i have been using their internet services for 11 days during my international stay.

Now with respect to this i have attached a screenshot for reference that supports what i say. I can send the itemized bill copy for reference.
I have been a loyal customer to vodafone for 10 years now i dont expect such kind of fraudulent behavior from them.
