Airtel — regarding communication alert messages receiving on account disabled warning

When my prepaid account going expire which is intact with my service activation charges as per new trai rule, i am receiving communication alert in my reginal language is pronounced in high severity/ in a improper /unfriendly way.

It is pronouncing as a warning. The message details in english is:
Warning! Your airtel mobile's outgoing services will be stopped on …. To continue the services recharge with your faviourate unlimited pack.

In english not sure how severe the word "warning" is but in telugu it somewhat terrying the customer and making him force to react or obey to the ask. The word "gentle remindder" or another high priority word is much better to understand the importance of the event and minimise the harshness and make the customer to take necessary action by making him understand the situation in a good manner. With follow-ups. The word "warning" in telugu is generlly issued by govenment body as per acts
