Airtel — airtel extra 2gb data not working

I got an offer with redmi note 8 pro that after recharging the data plan of 2gb i will get 2gb extra i. E (2gb +2gb)

This worked for the first 2 months but now the extra 2gb data is not working properly.

I want this problem to be fixed as fast as possible cause i am losing my data

I am including a picture in that it's mentioned that 4gb daily data is given but 2 gb doesn't work
