    Josh was not helpful and was very rude when assisting my mother and I with switching storage units. We tried to explain an issue we had with one of our storage units and he wasn't understanding it. We arrived at the office over an hour before closing time but it took time trying to explain our situation and to try to get it fixed. About 15 minutes before closing time, he told us that he was getting frustrated and that it was almost closing time which was very unprofessional. We tried to politely explain what exactly had happened but we ourselves were getting frustrated by the mistake done by the office that wasn't getting resolved. He ended up rudely kicking us out and telling us to come back the next day. He was overall very rude, unhelpful and pushed us out the door without helping solve the mistake that was done by the office. We went back the next day and were helped by Danny. He understood exactly what our issue was after we explained it and quickly worked to resolve it. He was very nice, knowledgeable and went above and beyond to make sure we were happy. I'm only giving 5 stars because Danny was extremely helpful and had no problem getting our issue resolved. I would've given a lower rating after our horrible experience with Josh which almost caused us to completely take our business elsewhere. Thank you to Danny for being wonderful and helping us and for being the only reason we chose to stay! ... Read more
