one Stop Moving and Storage Written Quotes from One Stop Moving mean nothing to them San Diego California

I received a written quote to do a flat rate move from this company . After accepting their proposal, giving them a credit card and scheduling the move they called me back and cancelled the move and breached their contract with me.  They told me that they had made a mistake and that the cost should have been thousands of dollars higher. Presumably I could have agreed to the higher price but I didn't and went with another company. I don't know if they make a habit of this but if they do it is a possible form of bait and switch. I would suggest anyone using this company use caution!!!
