Airtel — Airtel postpaid bill sent to wrong email

Address:

Chennai, Tamil Nadu

My phone number is [protected]. In the past few years, I have found multiple times that my email id has been wrongly stored with them as [protected]@gmail.com. I have absolutely nothing to do with this ID and I have informed cus care multiple times. Later, the bill was coming to correct email id mail.[protected]@gmail.com. I recently switched to paper bill and then back to ebill. When changing back to ebill, I informed to customer care that the email id he stated was wrong and the officer said it was changed. Again for the past two months, it is being sent to the wrong email ID. I escalated a complaint in their website . I received this email from them "We acknowledge receipt of your complaint, your reference no. is PO[protected] .We shall get back to you within 2 hrs." on May 27th. No communication from airtel after that and still the bill is going to wrong id. I was shocked to find that the ticket has been closed long back without any action or communication to my email id. It's unacceptable that they are sending my phone number and personal bill details to some other person for so long, and also I am having to pay the bill without receiving the bill. What action can I take against them for exposing my sensitive information to someone else for such a long time?
