Airtel — recharge description on website

Website:

www.airtel.in/prepaid-recharge

Hi sir,

I have done recharge on my mobile no [protected] with 399 amount (Date : 19-april-2018 12.15 -12.20 pm). The details of this recharge are 1.4 gb per day for 84 days. This is mentioned on your website. By choosing this offer i have done the recharge but i got 1.4 gb for 70 days. (Confirmation through message). It is very ridiculous. Please take necessary action and please all mentioned offers on my mobile no i. E data for 84 days.
