Exceptionally poor service

I received a call yesterday to advise me that there was no stock of Metformin through Dischem and Clicks courier. I was told I can pick up from Dischem or Clicks if they have stock of it. I specifically asked that both scripts be sent to Dischem and I will pick up only to find out today when I received a call from Crystal that another medication Annin is not in stock via Dischem and Clicks courier nationally. She suggested to take alternative as the supplier cannot advise when they will receive stock. Had she not called me I would not have known that the second script was not sent. I find this unacceptable, because this isn't the first time this has happened to me. Discovery Management should re-look at the service provided by medxpress. Changing a patients' medication that the patient is used to, may lead to the patient blaming any adverse effects or symptoms on the change of medication. Medxpress service standard has dropped in the past 6 months.
