I put a chair on FB marketplace for free this morning and had a message from an account with a man's name asking if it was still available. I replied yes and then he sent back another message asking if it was like one he'd seen and sent a link to a search engine results page. I stupidly clicked on the link but saw the page and couldn't see any mention of IKEA (which is where the chair is from) so sent him back a link to the relevant IKEA page. No reply.
A couple of hours later, I suddenly thought , what if it is a scam. His account has no details and a picture of a woman. I immediately changed my passwords for Facebook, gmail and my bank and everything looks fine.
Anything else I can do? I feel sick and so stupid. If I didn't input any details, can they still get access to anything?
