[dml-4550]

Just recently got the order, open it up remove the stuffing and saw that there was only 1 box.  same day contact the seller to inform them of the error. Seller says they will have to verify with USPS. Seller has since got back with me to inform me that the shipment was correct, and told me to contact Customer Service. I also sent Seller a picture of  box with the contents.  Not sure where to go from here.  Advise
