Dialing Innovations interview questions

Received a call and recruiter scheduled interview for the next day at 11am. Showed up the next day at 11am. Rung the ring doorbell 4 times before the owner finally answered, and proceeds to inform me that my interview was rescheduled. I asked if he had called me, he replied "no, I sent an email". After checking my spam folder, I see an email marked for 9am that morning. Don't waste your time with this company. They have absolutely no respect for your time and I can only imagine how they treat customers.
