This isn't the place for this. Get a lawyer and contact them. HN isn't a place to get in touch with YC companies for issues with them.

I believe OP is asking for advice on whether to contact YC about a problem they've had with a YC company, rather than trying to get a response on HN from the company.

I'm generally curious about this as well, does anybody know if there's a precedent for YC acting as an intermediary between customers and YC companies?
