      Complaint Type:
      Billing Issues
      Status:
      Unanswered
      I have had a storage unit at the Felton, DE location since 2013. I am active duty military who was moved to New Mexico and I updated my mailing and billing address with this company when I moved. Without notice my monthly charge went from $65 a month to $127 a month. When I called to inquire as to the increase they notified me they sent a letter to my old address in January 2024. They will not give me my old rate back even though I am unable to travel back to move my items out of storage. This is causing an additional financial burden on me and my family that I have no choice to pay so I can keep possession of my personal property until I retire and can make time to travel back to Delaware to remove my items and close my account.

      This company is totally unreliable , negligent and not trust - worthy . The following is what had happened to us . About two years ago , attracted by her promise of the state of the art security system and 24- hour surveillance, we opened a storage locker with Sentinel’s facility in Richmond BC. Last week , when we visited the storage to check out stuff , we were shocked to find that ALL of our valuables and goods in the locker was gone , emptied! We reported the incident to the local police immediately and then we found out the following : 1. There is NO sign of break-in into the storage . The door lock is intact, undamaged. Everything looks calm and normal outside. 2. The activity report issued by the company surprisingly shows that there is NO record whatsoever of other entrance and exit after our last visit , when at that time , we are certain that all of our belongings were still sitting in the storage locker. 3. Worst still , we discovered later for some reasons , the staff at Sentinel had decided to cancel our standard Insurance Protection Plan a few months ago without our written consent and even informing us , therefore leaving us totally exposed to this crime . 4. And this is not the end of the story. After long discussion with their senior management, we found that another insurance policy in some other people ‘a name worthy of millions of dollars was mysteriously attached to our locker account a few months ago , and their staff cannot offer any reason why this has happened , non they have ever sent any notification to us . This addition development was reported to the police immediately. I am an artist , and not only I have lost all of my major artworks in the last 10 years , I have also lost my collection of artworks by my fellow artists. It is heartbreaking and devastating. Even with such a major crime at the facility , up to the time of writing , seven days after the theft is reported to the police , the company still remains silent on why such a robbery in such manner can happen under their watch and 24-hour cameras surveillance! This case is still under investigation. I sincerely hope that those who are looking for a safe place for their valuables must think twice when choosing your storage . Clean facility, friendly faces, seemingly credible surveillance and so-called “advanced security system” may not be the only factors that matter . #metoostoragecrime Please hashtag and share your story if your have similar experiences #SentinelStorage #Storagecrime
