FIS Product Support Owner interview questions

Submitted the application on their website. Received an email from their recruiter at the end of a (typical) workday, explaining she'd like to set up a 15 minute phone screening the same day or the following day, and to respond back with available times. Responded to the email later that evening when I saw it, with my availability. I never heard back from the recruiter. 3 days later just shy of 5am I received an auto rejection email regarding the position. I forwarded that email to the recruiter and also responded through our original email trail, asking for clarification due to the conflicting communications. I never received a response. At the very least I would have appreciated a response as to why they were interested in me and then changed their mind. Found this to be very unprofessional. I suppose if this is the way things are with FIS I'd be weary to continue the process with them.
