Allstate interview questions

Received email setting up phone interview. Completed phone interview, was then sent an online test and was told that, if I passed, I would move on to an in-person interview. I passed the test, was contacted by a 2nd recruiter via email and was asked to give her a day/time that I was available in the next two weeks to meet in person with the manager. I promptly gave her my available dates. When a week went by with no response, I emailed her. I then received an email from the 1st recruiter telling me that the second email was a "mistake" and that they had already offered the job to someone else. VERY unprofessional. My opinion of Allstate went WAY down.
