I wish I could give zero stars. Extra space storage does NOT like to respond to people when ot comes to their storage being Auction off. I was told my personal family pictures as well as ALL my papers that were inside with my pictures would be returned. I never received a phone call from them in regards to my items. I had to call them repeatedly until I got through to the RUDEST woman on the other end of the phone telling me my personal items NEVER was returned. I will be in search of a lawyer because if my personal information is used Extra space storage will pay for it.

I was with them for four months. In that time, I set up auto pay at the start of every single month but for some inexplicable reason, I got emails and threatening phone calls for late fees because they were saying that my payment was overdue every single month. I believe this is them trying to scam people out of late fees by pretending to be incompetent when taking auto pay. Also, well, I have a storage unit completely full of my items they send me a silly little index card that tells me that my rate has gone up from $200 a month to $300 a month starting in one month. No room to negotiate, no discussion beforehand of a pending price increase, no incremental increase, Just a 50% price increase that you either have to take it or leave it. Because I’m not a fool and I’m willing to take the time to move my stuff I choose to leave it These people are crooks. I highly suggest not doing business with them. I don’t know about the rest of the national brand, but this location in Dover that doesn’t even have a fence to secure. The property is a Garbage location That is running the business like scam artists I’ll try to drive by to give some accurate photos of this trashy location when I can Here’s a photo of the notification they sent me to try and extort an increase of $100 a month on an originally $199 a month. And their BS response giving me a phone number to call just so they can pretend to Care is not going to get me back. There is nothing that will get me to do business with this bad of a company ever again. They made me have to get a moving truck and unload my stuff and find a new unit during the time I didn’t really have time to do it

It's unfortunate to hear about your experience with our Dover location. We understand your frustration regarding the auto pay issues you encountered during your four-month stay with us, as well as your concerns about the rate increase from $200 to $300 per month. We take feedback about our billing processes and pricing communications seriously. Please feel free to reach out to us at (603) 696-4422 to discuss this further so we can better understand what happened with your account and address your concerns directly.
