Horrible experience after horrible experience.
1. I reserved Unit and received e-mail confirming the reservation and notifying me that a lock would be waiting in the unit when I arrive. Not only was there no lock in the unit, the latch for the unit appeared to be broken so could not be locked. Chatted with a rep who advised me that there was no 7x10 unit available despite me having already received confirmation of the unit AND my credit card already being charged. Issue still pending resolition.
2. 8/30/2026 Not only is the loading dock on hartford ave not accessible, but the front entrance by the office was also not accessible despite the sign saying it would inaccessible until the 28th.
3. I wasted my time and those with me who arrived ready to move my things due to the above concerns. Thank God I didn't hire a big moving crew.
Spoke to someone Tuesday, 9/1 and explained all the issues including the miscommunication of the confirmation of my reservation, which stated that a lock would be waiting for me in the unit. But the representative explained that the lock has to be purchased so I said fine. It's just that there was a miscommunication in the confirmation I received stating that a lock would be provided, but honestly I shouldn't have to purchase a lock. With this poor service that I'm receiving and to date we still don't even have access to the loading docks on that side of the storage. Furthermore, there are no carts available on that side. So if you want to move anything in or out, you have to go to the far side of the unit on the other block. Anyway, the representative advised that he will just provide the lock for me and leave it in the unit. Went to the unit again today 9/3 and there was no lock in the unit. So once again , wasted my time....unfreaking believable!
