Airtel — recharge amount displayed in my airtel app and the benefits credited were not matching

I did a recharge today on airtel using my airtel app. Value displayed was rs 248 and the benefits were 1 gb data per day, unlimited calling etc for 82 days. When i completed the recharge, 3gb data was credited to my airtel account balance for 28 days. I refreshed the page again and found that the benefits i was looking for were available for rs 448. I refreshed 3-4 times and found the same benefits were available for rs 248. I took a screenshot of the same.
There is a bug in this app that sometimes it shows wrong amount for different benefits.
Please get this resolved as soon as possible.
