02-08-2026Talk about Bait and Switch! These predatory deceiving shameless thugs went from $89/month to $189/month at the end of my initial contract! I had to deal with a broken gate for about 7 weeks by being forced to enter far away and had to wait a few times for other tenants to move so I could get through the only tunnel to get to our storage. I will definitely be OUT AND NEVER USE THIS COMPANY AGAIN. I tried calling and the representative(Jacob) "helped me" by offering me a $179/month offer. What a joke!
