Vodafone India — i am getting vodafone bills after full and final settlement for deactivated sim.

Address:

400079

Hello,
I had vodafone corporate sim card for mobile project related work. When my project closed i raised request to corporate assist to deactivate my sim. They sent me email regarding sim deactivation after i paid all amount of last month mid august-17
I am getting emails for payment of previously paid bills ex, june, july august.
I wrote 6-7 mail to them to look this misunderstandings but they always send regret email and promising that you will not get these kind of mail from next month but still it happens repetitively.

Thanks,
Nilesh navgrahe
