Medlife — no transparency

They say the order is always confirmed and is being processed. They make the confirmation phone call too.
But at the end of the day, they will get to know that the medicine we have ordered is out of stock and simply send a message saying the order has been cancelled.
They call back on our number, giving all their promotional details and not a piece of information about our need.
They only ask us to register, to get our phone number for their business promotion but never to deliver our need.
Why cant they be clear about the drug being out of stock on their website or app while we to tend to order? Why only after we place the order and take a breath seeing that fake confirmation green dot?
Transparency is all we need.
And yes trust is far gone too.
