Vodafone India — wrong billing services deactivated

Address:

5/2 mgsf Lucknow cantt, Lucknow, Uttar Pradesh, 236002

I was travelling to mizoram and I have been charged rs 40000 as data used on international roaming. I have not travelled abroad at all how can they charge international roaming for travelling to remote locations.
They informed me that my data usage limit is 7000 why did they give me a grace of 33000 . Now my services are deactivated for past 6 days I have written to every complaint channel in the company but no one seems to pay any attention please help my Vodafone no is [protected]
