Hey I know how frustrating that can be not getting the care you need and having to wait around calling back constantly just trying to speak to someone.
I recently had a (somewhat) similar situation with trying to get my son’s hand casted with an ortho after he broke it on a Friday night.
I had to keep calling asking if his ortho had gotten the refer and could see him. It took until the 5th call before someone told me his Dr was gone on a military deployment and that’s why nobody had called me back on the referral.
In the meantime I called his pediatrician to get a referral to another clinic to get him care. It was Monday by 5pm before I was able to get him seen.
No where near the level of what you are going through, just wanted to offer some solidarity and the advice to just keep calling and advocating for yourself.
Eventually you will get someone who is willing and capable to help, even if, in the meantime, it feels like no one cares that you aren’t or someone you love isn’t getting the care that is needed.
