non delivery

These people are supposed to be delivering pain medication for a pharmacy. They cannot do it in time, which is serious and means the patient either has to drive and collect their prescription or go to a new pharmacy. DPD is completely unable to change my address on their system and just keep sending me automated messages that they can't find my house. This is for pain medication that needs to be taken every day. Pathetic. Stupid choice by the pharmacy too. Clearly they don't take their role seriously. I have been subjected to this for two consecutive months. I cannot do it any more.
