iPhone 14 blocking calls on its own

I have read many post about iPhones blocking calls on their own, none of which give a solution that seems to work. I even purchased a new iPhone same problem! I unblock them and they slowly return to blocked. I called apple and they act like this has never been reported before. I have tried taking off call filtering, changing focus settings, unblocking and restarting, updating the phone. I’ve tried it all. I went into the Apple Store and they said, “oh well it’s not happening now, so we can’t help you”. To me it’s very unlike apple to not try to fix something that according to the internet is a common problem. I love apple, but I’m just about done ✅ Apple knows this is a problem and is doing nothing to fix it. I wondering if a new Apple ID would fix the problem. Start fresh, but then I need my photos and contacts to transfer. I’m afraid that this bug will transfer with it and I’m now convinced it’s attached to my apple ID.
