Ok so our storage unit got broken into and I was so upset on the drive there to see what they took. Dang they took a bunch of tools and things...to make a long story short. I would like to thank the on site manager. She genuinely cared and made me feel better by explaining everything from watching video cameras to getting police report to filling insurance claim. Thanks so much for calming me down. You are great at your job.ššš¼
