Airtel — complaint against my airtel bill sent to other id

Address:	Ghaziabad, Uttar Pradesh, 201002

Hi,

Every month airtel sent my bill to my email id but this time they sent my bill to one of the friends id without any verification. I received a text regarding this. My no. Is [protected] and they do not have any record for the same that who have asked them to send my bill to other id. Any kind of a tempering with my account is illegal. I want this to be actioned as soon as possible.
