Gametime United Ticket Operations Associate interview questions

Started with a phone interview that went great, followed by another phone interview that went well. They expressed interest in a third interview that would be a panel interview. They asked for my availability and I sent it to them. I then received word that one of the interviewers was out of town, then I was asked for more availability. After that, I could not get a response. Emails, texts and calls. No response. It was extremely unprofessional. They are fans of ghosting. Just give me a response and I will understand. But no, nothing. Really embarrassing company and I will not be buying tickets from them. All it takes is a response, especially after they expressed interest in a third interview.
