Airtel — ESIM deactivated without notification

I am currently in Canada and had my India number as eSIM in my iPhone. I changed my phone and transferred my eSIM to new phone. However, after transferring, the eSIM was deactivated by Airtel after a couple of days. This has impacted me a lot as all my important transactions were being done using that number and Airtel has refused to provide any assistance in this matter. Moreover Airtel asked me to come back to India to get the SIM activated. Please note I do not have any blood relative in India and I cannot travel to India as well.
