Customer service was excellent, but I do have a significant concern. I have used this moving service 4 times , with the same furniture. My my moved usely last 3.5 to 4 hours max for 2 bedroom apartment, one of the rooms were onlu used to store a couple of boxes and 1 headboard. My move this time lasted a little over 8 hrs. which left me with a huge bill, I guess they knocked it out of the park this time.
