1mg — Order getting cancelled

My order gets cancelled twice after accepting it that to after waiting for 24 to 48 hrs as I was in a need of the medicine urgently. Why are they accepting orders if they don't have the medicine. This kind of service is life threatening as the medicine is very important to me and I cannot afford missing even a single does otherwise I might have to get myself admit. They shouldn't have accepted the order in the first place and this happened twice
