Vodafone India — getting bill generation email for payment even after closing the account

Address:

Chennai, Tamil Nadu, 600041

Hi team,

I have been using a vodafone postpaid sim for the past one year and i have paid all my dues and wish to close my vodafone services as i am highly frustrated with the service, but still am getting bill generation emails for novber and december month eventhough i made the payment on october. This is ridiculous and i have never seen such a worst customer support service was not able to contact customer support as i don't have a vodafone postpaid number.

Tried to reach the support on a toll-free number too but that's not working. Why i am getting bill notification every month??
If vodafone is using advogate help. To close the outstanding dues then the procedure should be perfect. I am highly frustrated by the negligence of your service. Please find the bill payment and other details in the attachments.

Regards,
James
