Airtel — Email id not getting updated in airtel thanks app

Email id not getting updated in airtel thanks app

my email id is entered misspelled by airtel executive at the time of new sim now its not getting updated and because of that airtel not accepting my email
weird rules of airtel that it wont accept mails from non registered mail
sometimes i wonder have i made a mistake by porting from idea to airtel
as its impossible to connect with a customer care executive from non airtel number

lot of issues and not friendly with customers
