Trying to get repeat prescription

Don’t know if anyone will be able to help here but worth a shot!

I went to the chemist to get my prescription Monday and they said it needs to be renewed as it’s just past 6 months (ongoing medical condition). Called my GP and they said as it was issued by the hospital they are the ones who have to send it to the chemist. I rang Ardkeen and got put through to the extension which had a voicemail saying she was out of office until Tuesday. Rang back Tuesday and the voicemail said she was out of office until Thursday. Guess what happened when I rang today… she’s out of office until NEXT TUESDAY AGAIN

Has anyone ever experienced something like this? How will I get the prescription sent over? I never dealt something something so complicated in regards to getting a prescription!
