Now while I fully understand that this CAN happen, it SHOULDNT and their lack of accountability and overwhelmingly POOR response to our beloved trailer being stolen from THEIR PROPERTY, is disgusting. TRAILER WAS STOLEN FROM PROPERTY MAY 12, around 8am. ABBA STORAGE DID NOT CALL OR NOTIFY US UNTIL 12pm on may 13, today. The day I'm writing this review. I am just now getting home after an absolutely unacceptable experience with this facility and its employees. My family and I have been renting a space at Abba storage in Concord for approximately eight years we have stored our Coleman travel trailer there for the entirety of this time yesterday morning somebody came in behind another customer with a U-Haul truck and hitched it up to our trailer and stole it in broad daylight, then on top of it, ABBA Storage, did not call and notify us about our trailer being stolen from their property until approximately 12 PM the following day May 13, the employee at the front desk, lied to me and said that she called me and left me a message after going through my phone records At length she never once called me nor did she leave me a message, hence our shock and surprise finding out the day after that our property had been stolen. When we arrived on Abba Storage's property to discuss this with them. They also told us that they have not filed the police report or called the police. They did not notify anybody about what happened or about our trailer being stolen from their property. ******** EDIT the police officer confirmed that when asked WHY they didn't notify us sooner regarding our stolen property they said they were " too busy" .......! Woman at the front desk also said they know and have known that people have been renting storages to steal peoples property! So that was nice to know and find out! Supposedly the manager does hourly checks on the property to ensure that all trailers and property looks like it's undisturbed and nothing looks out of place, clearly they are not doing that because my trailer was taken so boldly , at 8:22 AM. When asked direct questions from the police officers about the maintenance of the facility and their protocol and procedures. Those were pretty much unanswered and a lot of "uhhh" and we "didn't see it!" Those were the responses. They have been absolutely unhelpful. They have been unapologetic. They did not once offer any sort of consolation or apology for what it happened. "24/7 camera monitoring" should provide you little to no comfort here-- Their cameras are antiquated and are somewhat fuzzy and blurry. When we were going through the footage to review what we could find and what we could see on the footage in order to persecute this thief-- we could barely make out anything. The cameras on the facility are not monitoring every single angle that you think that they are and they certainly don't have high quality footage in order to successfully obtain evidence. I'm not even sure there are enough cameras to make sure that they're capturing everything on ABBA's property. The response from ABBA was extremely disappointing. They have been rude dismissive and frankly, they haven't taken any responsibility for this happening at all. Do not store your personal belongings or property here they do not care about their customers or their personal belongings, and that is a fact.. Their gate is open literally all morning we witnessed tens of cars, simply following each other in back to back to back --and while I DO understand that at a storage facility tailgating, and that kind of stuff is of the nature, it is ALSO the responsibility the storage facility to maintain safe environment for their clients and for their clients property!!!!! If you have property stored here I would recommend you relocate it, expeditiously.
