I had just arrived in San Diego and needed a space to put my moving boxes since I was going to be staying at an Airbnb for a couple of weeks. I decided to use this location since it was nearby and rented a space online. I paid $95.84 total. When I arrived there, I realized the space was inconvenient since I would need to climb a ladder to put the boxes up top. I immediately went to the front desk and requested to switch lockers. The gentleman was nice and did it for me. I was charged again $116 and was told I got the “transfer fee” of $10.00 waived. I didn’t realize at the time that I was paying double for simply switching lockers, and mind you, I hadn’t even loaded anything into the first one. I stayed with the second locker for a couple of weeks (less than a month) and asked if I could receive a credit for staying less than a month. He said no due to company policy, which I understand. However, when I asked for my refund from the first locker, he told me he needed to speak with his supervisor. He later called, saying that they couldn’t refund the first locker that I DID NOT EVEN USE. This is completely unfair to consumers who have no ability to fight back against a charge that shouldn’t have continued since it was never used. I’ll never rent a locker here again. BEWARE
We apologize for the double charge and lack of refund for the unused locker, Michelle. Please contact us at (858) 252-7228 to resolve this billing issue.
