Pharmacy direct failing to deliver and failing to take responsibility

Time and time again I'm sending emails, calling these people because I am left days without medications because of their incompetence. I am constantly calling, right now my meds have not been delivered. Three days ago I had to call because I had run out and they promised to roll it out as urgent but I'm yet to receive it which basically means I have not been medicating because PD fails us. Why we are forces to rely on PD is beyond me because clearly they don't know what they are doing. If one dies because of this they can really expect a law suit on their hands. These people are taking our lives for granted, I have really had it with this nonsense. Somebody better take responsibility for this.
