LHH Web Application Developer interview questions

The recruiter contacted me on linkedin and told me that I would like to make an appointment with her for an interview, and then I replied to her, two or three times, and she replied three days later when she was single, telling me that I could interview on Friday, and then on Friday this day The recruiter told me the interview would be scheduled for the next week, and the week went by, and she didn't contact me. The whole process is very disrespectful, if you don't want to make an appointment with me for the next step, why contact me, and three interviews were arranged and canceled. The recruiters at this company are very rude and disrespectful.
