Gusto support has been ‘looking into it’ for 3 weeks while our contractor in Germany hasn’t been paid

Three weeks of “we’re escalating this” and my contractor in Berlin still hasn’t gotten her October payment. She’s been patient but I’m honestly freaking out about the legal side of this. Germany doesn’t mess around with labor law stuff and I have no idea what our liability looks like if this drags out longer.

Anyone dealt with this? Do I need a lawyer or am I overthinking it
