Hi BigDean,
I would take it back from where you brought it from. Being brand new it should be spotless. If you can't take it back to them get them to pick it up. Do not let them get away with it. They have a duty to make sure it is fit for purpose. I got a second hand MoHo from a dealer & if i found anything not right with it they bent over backwards to get it sorted and that was on a 12 year old MoHo.
