After speaking with someone to check box availability & pricing, I drove to their 1600 N Nellis location about a week later (Oct 17, 2019) to rent a box. 3:02pm in the afternoon the Open sigh was lit but the door was locked & nobody was there. I called but the phone was switched to a fax machine.
As I sat there until 3:30pm, I called that store 4 more times (still got fax) & their main location at 1155 E Twain over 30x, only to get a busy signal. Finally gave up & left. Like most people, I prefer to have access to my mail whenever I can get by there during there business hours. Open sign on w/ business completely unattended just seemed odd. Almost like things weren't on the up-&-up.
Spoke w/ the owner (Matt) today to let him know what happened & got the distinct impression the he didn't care (except to say that the employee at the Nellis location had gone home to Mexico for something to do with her citizenship), & that someone else was supposed to be covering the store. And apparently a fax (over 30 minutes long?) had kept me from being able to reach someone at the main store.
Found out today that although they're not a member of the BBB in Las Vegas, I'm not the 1st person to file a complaint.
