Ticketswap legit for anne frank house museum tickets?

wasn't able to get tickets for the museum on their official site (sold out for the days I'm in Amsterdam) so bought a ticket off of Ticketswap. It allowed me to instant download and the ticket has a QR code but it doesn't look like a museum ticket - it's a pink page with the sellers name and the time of entry. Not sure if I've been scammed since it doesn't look like a museum ticket for sure.

Has anyone bought tickets for the anne frank house museum from ticketswap? Did yours also look like a pink page?

Want to verify this before trying other avenues to get the tickets!
