The worst experience. They promise a delivery date and then as soon as you make the payment, they will change the delivery date. These people don't know the importance of delivering medicines on time. They will wait for you to reach the hospital and then deliver you medicines at your funeral. Customer service is of no use and can't do anything. Why promise something you can't do. There 10 different apps I could have ordered from, but I saw yours had an earlier delivery date and fell for it.
