Airtel — No customer care service

I have mailed to [protected]@airtel.com and they told me to send a screen recording but sadly when I send the screen recording I got a message that tells, " The Email you have entered could not be found" and suggested to mail it to [protected]@airtel.com. Again [protected]@airtel.com told me that My Email didn't register against my airtel number and suggested to call 121 to register. By calling 121 I didn't have any option to register or talk to a customer care executive instead, though, I didn't opt for any language but I got Manipur mixed up with Hindi. I am ok with Manipuri but Hindi I completely don't understand. Plus I can't verify my Email through Airtel App. I got a message to verify my email but I just can't verify it. When I clicked on the VERIFY button Airtel App opens up and no further instructions to go ahead and verify it.
