"This 40ft High Cube container from On-Site Storage Solutions has been perfect for my business. It's spacious, secure, and the rent-to-own option made it affordable."

"Prices are.great. But the communication is terrible. You call for delivery and they tell you to hang up and request it via email. Oh thanks wish I knew that... And because I do not own or operate your business, I don't know what to write ... Or not to write in this email. Because I did not know how they own or operate their business, they showed up with my unit with the door loaded in the wrong direction and the driver tried to tell me it wasn't his fault... No one called to ask where I wanted it or what direction I wanted the door to open to. Because we were moving and selling our home I had a lot encounters with the staff and the communication is just... Aweful. UPDATE Read below their response. This are bad business practices. You rely on the customer to think of all the intricate details? As a business you have the responsibility to assure the customer experiences excellent service, including guiding them through details that are very important, but they may miss. And by the way, the first time I had it delivered, the rep asked me where it should go and what side the door to open to. The subsequent times, I had to bring that up. The last time I forgot and look what happened. Either you argue or learn from mistakes and perhaps improve your company. It's up to you."
