Vodafone — Number cannot be deactivated

Address:

Kolkata, West Bengal

Requested to deactivate vodafone number [protected] on 17 / 06 / 2015 but request was not completed by vodafone and no actions were taken.
Now we moved to united states and dont have any local vodafone number.
Registered email id in the system is reshmi. [protected]@gmail.com but was updated by vodafone executive wrongly as [protected]@gmail.com
When we placed a request to deactivate via email vodafone is asking to send email from registered number or send sms to 199
Sending email from registered number is not possible as email in system is wrongly updated and we don't have access to local india vodafone number.
Vodafone employees have come to rented apartment, address given at the time of registration and have harassed all present at that address.
