So I was in a bit of a dilemma. I need a storage unit ASAP so I called Yvonne at the extra storage in Colton. It turned out that the one I got was too small and she immediately accommodated me as I upgraded to a larger one and then to find out I still didn’t have enough space for all my stuff so when I called To get an additional storage unit again, Yvonne was extremely helpful, very polite and eager to accommodate me Thank you so much, Yvonne. I appreciate you and all you did to help make my moving experience a little easier cause we all know moving sucks.
