This is with reference to my order id: or8775lq-00aa for which i had made complete payment. But after 2 days i was informed that the medicine which i have ordered is out of stock. While i was ordering, the medicine was showing in the website and i placed the order. Also i have done the payment too. The order was done on 2nd august 2019 and it was committed that the medicine will be delivered by 4th august 2019 by 10 pm. But suddenly i received an from "im-medlif" informing me the order update as below:

Order update: dear customer, full stock of amexidil are not readily available. We are trying hard to source the same from anywhere in india. You will receive further communication by 6/8 11:00 am. Inconvenience regretted.

I don't understand, how it is possible that suddenly the medicine is out of stock after 48 hours of placing the order. Medlife is making fool their customer and displaying wrong information on their website about the stock of medicines. Also they are taking order from customers and later they are informing that the medicine is out of stock. They should display the medicine stock correctly on their website.
I would like to highlight this to higher management of medlife and escalate to them to intervene so that there is no such bad experience happens further with any other person.
