Incorrect selling

They offered me a explorer and that i could pay it off in 24 months, i repeatedly told them i have dual view and i need 2 explorores and was lead to believe i would get two, i wouldnt have taking the offer just for the one. they sent the explorer with the courier and it took me weeks to get them to respond and now get told they only give one explorer to new customers and i have no option but to take the explorer.
