I had a similar problem. I think my listings were deleted or blocked due to fraud checks. Check all verification options for phone email and id. I had to upñoad my passport (as photo id) in addition to my profile pic. Then I had to take a live selfie which it then compared to my other pics. 3 attempts before I got one to match. I understand it also checks a variety of things to make sure the listing looks real. In my case I wrote that refurbishments were in progress so I had a disproportionate number of external pics to inside ones. So check for anything that might cause them to consider your listing a scam. They won't tell you this is happening but they will call you free and help you resolve it if you persevere. Jonathon was the chap that helped me. I had a few wasted calls till he helped. I was told up to 72 hours to wait but it took less than an hour once I corrected the issues.
