If you are within your 14 day return window, give it back and get what you want. If not then I believe you are out of luck with the company. Someone can chime in on this and tell me if I'm wrong, but since you have the more expensive phone why not trade it to a friend with an S7 that wants an Edge. All you would have to do is swap the sim and Sd cards, factory reset the phones and put your new edge on your account. Of course your are still responsible to fulfill the terms of your contract by paying of the phone but you will have what your desire. If you can't find a trading partner you could pay off the phone, sell it on the secondary market and purchase a new phone and install your old sim card.
