8 PACK -Acoustic Foam XL Bass Trap Studio Soundproofing Corner Wall 12" X 12" X 12"

I have been ordering lots of these as needed to complete my project. They always come in packs of 2 corner wedges that make a cube when fit together. First time ordering from walmart and the image shows four wedges and description says 2 pack, so as they are sold everywhere else and comparing price I am expecting 4 corner wedges, two cubes. I only received 2 wedges, one cube. Contacted seller and they told me I should have received 4 wedges in one package. I sent pics of the one package with one cube, two wedges, that I received. Their response was I should only get two wedges. I think their product information contradicts itself and even their staff was confused. They have not responded with a resolution, so I am looking for another supplier. Basically I received half the product or in other words paid double the unit price if you compare the the price everywhere else. Not happy, bad experience with Walmart and unacceptable behavior from Mybecca. Really feel taken advantage of.
