@nezumih It's not a device issue, it seems it's the clinic itself. Is there a US body that oversees medical providers or administration processes? They'd be the people to go to. Or any insurance regulators - they might not be the exact party causing the issue, but they might be able to point OP to who to make the complaint to.

In most cases here, as far as I'm aware, you have to start with making a formal (in writing) complaint to the clinic first though. I'm presuming OP already has.
