Vodafone India — leaking customers personal information

My email was wrongly associated with a vodafone customer. So i receive regular communication that vodafone send to its customer including monthly bills. This reveals entire customer activity to me. I notified about this to vodafone through call, email, etc., (Not once but 8 times). Still i continuously receive mails from them and no action taken against the complaint.

I guess vodafone is more interested to retain its customers for money and dont care about customer privacy. Couple of mails from vodafone had a number it to call for any issues. When talking to them i found, they really dont care about customers privacy. When i said i am getting such mails, they just said we will check and update, but didnt ask any details like my email id, associated customer details (Acct number / mobile number). Without any information, how are they going to solve the issue??? I called again to provide information, but the rejected my calls. I tried to 3 different numbers everyone answered the first or second time, from then all were avoiding my calls.

Not to forgot 4 others, who requested all the information and assured to remove my email id from the account, but that also never happened (And this confirmation was provided in august, 2017... I guess 3 months is not enough to remove an email)

This shows how good they care for their customers and to protect their personal information. Shame on them!!!
