Possibly just messed up- Scam visa??

I am SO ANGRY at myself and totally humiliated but I need help fast.

I just went to get my UK ETA visa and used a site that is almost certainly a scam. I was totally exhausted and wanted it done before a trip in June and it all looked like the site I had looked over previously so I just went through it and...it was almost certainly fake. The charge was way too expensive and I didn't eben realize until I hit Accept.

I have no idea what to do, I've never fallen for a scam before and now they have my passport info. I need advice fast. I locked my credit card but it looks like it already went through so all I can do is prevent them from charging it again. But I am shaking thinking of my passport info out there. Anyone have experience with this???

The site was TravelVisaSubmit.

I am just so so embarrassed and lesson learned so PLEASE don't just comment yelling at me or making fun of me, let me know how I can minimize the damage.

Thank you!!!!!
