Chronic medication late delivery

I received an SMS stating our chronic medication script has expired (only when the delivery was expected end January). I requested a script from my doctor and sent this to them on 2 Feb 2015 at 11:23, requesting urgent delivery. On 4 Feb at 15:30 I received confirmation that my script was received. On 9 February I called and Paula said she will send request for urgent delivery through. On 11 Feb I received SMS stating that delivery will take place within 24 hours. Yesterday I called again and was told the delivery should reach me on 12/2. I called again this morning and spoke to Sarah who said medication was dispensed this morning. All this time I have been without my medication (I told this to all I spoke to in the call centre! I told her I was going away for the weekend and demanded that my medication be delivered before 12. She is sending an e-mail to the Dispatch Manager, requesting her to call me. Now the wait.
