"Regularly terrible"

I’m struggling with several health issues which are quite serious. In the last two years my life has completely changed because of these things. When I call, the person answering the call is not use and officious, even sounding angry that I’ve bothered them. Often I have to call several times over a period of weeks before a doctor will call me back. My own doctor regularly fails to do what he says he will do. Denies he ever suggested what he said he would do. I’ve received incorrect prescriptions numerous times even though I have called to correct it. My health is getting worse and I believe I’ve received bad advice too. I will be changing surgeries as soon as possible.
