Airtel — Data balance issue

I have raised a ticket earlier.My Service Request number is CLCCV3CHN[protected], and it was dated on 24th December 2022.

As per the earlier discussion with your customer service representative, I was informed that I need to turn off my mobile data when not using it to avoid data loss. I have been following this instruction and turned off my data during the night. However, this morning (8/2/23).I was surprised to see that 355 MB of data was used during the night when my data was supposed to be off. I am the only one who has access to the phone.i am sure the data was off. When turned on data this morning, it is showing 1.7 GB left in your Airtel app.

Upon checking the internet, I found that many other customers are also facing similar issues.I see similar complaint in this website also . It is clear that this is a problem from Airtel's side. I am attaching a screenshot of the data monitor of my phone as evidence of my complaint.( You can see daily usage at the bottom of the screenshot, it also has the date too.) Only 41 mb data is used at the time of taking the screenshot.
