HHGREGG delivered the wrong item Internet

i bought a stove that was for about $400. When they came to deliver they delivered the wrong item. We went to the store and they said they put that price buy accident! We talked to the manager and he said that he wont give us the stove for $400. We were fighting with him a lot and when i said that i will report this case the manager was like he could care less. If you buy from this store just make sure the numbers on the receipt and on the item match, or else you'll get stuck like we did.
