RBL Bank — RBL Bank refusing to cancel auto renewal of R Shield and refusing to connect

I have RBL Bank Credit card and I activated R Shield last year and now I don't need it. So I tried to contact them to cancel it and they are refusing to cancel it saying my email id is different. I use the same gmail id and just because a dot is missing from my gmail id, they refuse to cancel auto renewal. I tried to call all the customer care numbers they gave and all of them are just IVR numbers, I am not able to reach any human personnel who can stop auto renewal on my card. I even changed the email id on the app and still they are not processing my request.

They are fraudulently keeping me away to charge me for 1 more year. I don't want to be treated like this by a fraud company. I gave them my phone number to call, they refused and every time I contact them all I get are messages to contact same email id and phone numbers, it goes in circles. I'm already tight on cash and abusing customers like this should stop.
