Missy deserves a shoutout for being awesome. As soon as we started talking her attitude was so positive I instantly got in a better mood. We then thought we could leave items at the dumpster and she called and kindly told us we couldn’t. We were pulling in to pick up our things and she had already called her boss to say the things will fit in the dumpster and it comes tomorrow! Saved our tiny car a bunch of trips back and forth between a dump. Really the level of customer service she provided is top notch
Edit: Missy deserves a raise!!!

These guys are totally amazing and I was extremely impressed! I moved out of the unit and was worried about maybe getting charged for the upcoming month even though I had moved out and when I called they had already checked me out/made sure my unit was no longer getting billed/closed that account for me - it was awesome!
