Medlife — order neither delivered nor cancelled

Website:

www.medlife.com

I ordered medicines on medlife.com on 7 jan 2019. I got confirmation call on 9 jan that my medicines will be delivered by 11 jan. After waiting till 14 jan i contacted medlife customer care.. They said to wait for 24 hrs so that the order can be completed. I did so. Again i contacted on 16 jan, i was told that my order has been cancelled and i will get my refund in 24 hrs. On 18 jan i submitted a feedback in "write to us" section on medlife.com and i got call from medlife saying that my order is not cancelled and will be delivered in 24 hrs.
Now, i m still confused what is going on with my order. Also in my medlife.com account it is still showing order under process and will be delivered by 11 jan (And it's been 21 jan today). Not getting any proper response.. 😢
