When I called to inquire about a rental property, the young lady that I spoke with did not seem very interested in my inquiry. I arrived at the office with everything and more in hand to apply, after applying I did not receive a call or email with an update on my application, I then call to follow up myself since clearly no one was going to reach out to me. I was told that my application was denied. (FLAT OUT) They did not even have the curtesy to give me a reason.
