Airtel — Email Id Updation

Hi
I am Gopal a resident of Chennai. I am seeking an E-sim for my newly bought Apple watch. being regular user of Airtel telecommunication, I applied for esim to Airtel. But my requestion was rejected mentioning invalid email id, however that’s my personal email id and even executive from airtel are also communicating with me through same email id. I requested to provide more details and called them several times, but all my requests fallen into deaf ears. It’s been a month and I lost my hope to get any details regarding this, hence requesting you to help me to know what’s exactly the issue is I am attaching all communication details for your reference.

I am so much frustrated with their service, this is only the last hope where I can get my solution so, please do needful.

My Email Id is: [protected]@gmail.com
