I had 3 great interviews with the same company and then got completely GHOSTED!!

I had 3 great interviews with this company for a Customer Account Specialist - 1 phone and 1 video. I sent thank you emails to everyone and after 2 weeks (they said I would hear something in a week or two), I followed up for an update. \*Crickets\* No call, no response, not even a rejection, just nothing. And then about a week and half later (still job searching!) I saw they posted for the same roll I was interviewing for. I was pissed - at least give me a rejection. And like I said, the THREE interviews went really well, so I was initially really hopeful. My husband thinks it's a ghost job posting, but I don't think they would go through the whole process of multiple interviews. I was thinking of reaching out again, even if just to way WTF. Being unemployed and job searching is stressful enough - I don't need companies messing with me!
