Struggling to find housing or even be contacted by property managers

I keep applying and applying and paying these ridiculous application fees and CALLING to check the status of my applications!!! And I keep being told “oh the realtor is out of the office well have them call you” or “I don’t have any information about that” (?!?!) or I don’t hear back period!! What am I supposed to do???? I’ve been looking/applying for nearly a month straight. I’m online every day. I’m vigilant and I’m looking out for new listings and I’m so responsive. Not only that, my previous landlord and boss are responding timely as well!!! What else can I even do on my end???

One rental I applied to, and called multiple times for, got rented to my coworker who applied nearly a week after me! And when I called to ask about it they kept saying they’d call me back, and they just never did. That was IMS/Bindel. When I called Pacific Coast TWICE about a rental I applied to, I got told they “didn’t have any information” about my application and couldn’t tell me anything, which makes no fucking sense. When I called back AGAIN to see if I could schedule a viewing they said the realtor was out but they’d have her call me. This was DAYS and days ago. Today when I checked their website, the listing was gone. I don’t understand what I’m doing wrong. I have the income, I have the references, idk what else to do but i’m stressing out so hard it’s starting to affect me physically as well. Does anyone have any advice? I mean I think I’m doing everything in my power. I try to reach out and contact, I keep going on tours, I don’t understand but I’m losing my mind.
