My experience was similar with below but I look at it through a different lens. Yes they charged me double what they quoted but they also quoted about 5x less than anyone else. They packed up a 26ft uhaul truck in 2 hours with some very heavy furniture. $400 to move my entire place was money well spent.
People need to realize there are some things you just can't go cheap on and moving is one of them. Sure, I could of said no to the $400 they quoted me once they arrived but I would of got worse service from someone else. Btw - they will quote you before touching anything which I liked. Not sure what everyone is talking about with them quoting after the fact.
