Recon Force Advantage

Bizarre experience. Shipped from amazon and from a different seller name. Showed up with no invoice for this purchase but rather with a gift card receipt with no explanation. The shipping details for the shipper showed nothing until I followed up. Seller dropped the price of the item immediately after purchase and would not offer a credit. Did respond quickly to my messages but did not directly answer my question about whether this gift package I received was indeed this purchase.
