Terrible service

Pharmacy direct don't have any communication among themselves and the patient's that they send medication to. I have paid in advance 6 days ago as requested before theycsend out my medication and sent through proof of payment via email, and it was acknowledged, but the meds were not sent out. I called in and sent emails again stating that payment was done and asked when will my medication be delivered as it is chronic medication for diabetes which is taken daily. They have no answer for me and just say they have requested for it urgently. The pharmacist don't even call back after I was told I would get a call back. How can you service chronic patients without proper answers. The lack of care could be detrimental to many patients because of non delivery.
