Unsubscribing from insta alerts

Need an easier way to opt out of insta alerts - there is no option in the app or in the equitas internet banking portal. There is no link in the email as well. It just says:

“To unsubscribe/ modify alerts, please contact our customer care @1800-103-1222 or visit our nearest branch”

It is near impossible to connect to the customer care and a visit to the branch is too cumbersome. Please provide an option.
