Airtel — wrong data scheme processed

Address:

Mumbai City, Maharashtra, 400068

I have recharged for the offer rs. 399 which includes unlimited calls, 1.4 gb/day 4g data, 100 sms/day and validity is for 84 days from the airtel app. But the scheme that was processed is rs. 399 for 70 days.
I want to know which scheme exactly is activated and if not the 84 days one then do cancel the scheme and reverse my transaction.
I also have screenshots for you to investigate. I can share it.
If the scheme cannot be processed, i hope some company executive will give me a call for rectification and clear understanding of this glitch.
