Doctor ghosting on refill request

I've been trying to get my Gabapentin refilled since noon on Tuesday. I've sent 3 MyChart messages and called 3 times spending 2.5 hours on hold total. I only actually got through to a person once, this morning, and was told "oh yeah we have the request, just waiting on her to approve it, it should be really soon". No response to any of my MyChart messages. I tried to call again an hour and a half before they closed today because the pharmacy still hadn't received it. First time I waited for 43 minutes for it to say "system error try again later" when it was finally my turn in the queue. Called again, waiting 44 minutes for it to be my turn for the same thing to happen. Now they're closed and I'll have to wait until at least Monday. I am fucking livid and I'm in so much pain. How is this not medical malpractice? I've been without it for over a month. I stopped taking it because I felt a lot better and don't like how it makes my brain feel. But now I'm having the worst flare of my life and in dire need.
