No registration of meds after providing the script

I have on 10 March, received an sms reminding me that a script is required for medication renewal, the same day I saw the Dr, and on 11 March, I faxed to *** the script, after successfully faxing I called ***and held for 3:12 minutes I the call was dropped as I identified it went thru, upon saying good day< it was put down, the next day, 12.03 I hang on for 4:08 min the call was dropped, Friday, 13.03 I held on for 4:27 the same happened, I then wondered today, why since 2011, do I fax the require documents, and still waste my time and money, by phoning to make them aware my script has being sent, for them to start working on the extension of my treatment, whilst people are employed to do just that.
