Iberia office supply quote one price charged another New Iberia Louisiana

Hired Iberia Office supply to move a truck full of furniture.They charged me $180 which was fair,two years later I called to move same stuff same distance and was told $200 OK still fair,That was for 3guys 1 truck, 6 guys showed up stuff was moved handed bill $400 when asked why I was told 6 guys did it faster but I was only paying for 3 in that case you can't have your furniture and we will not unload it.Paid the bill and went in to  their office the next morning spoke to the owner he said bill was fair for 6 guys but I only hired 3 because that worked last time.I was told  no refund.So if you even think about useing these people GET IT IN WRITTING FIRST.I trusted them being we were both local and got screwed..or better yet use some one else
