HATE is a pretty strong word. Maybe dislike. AFAIK, you can return any phone to Verizon, ATT, Mobile, Apple, etc etc for 14 days to 30 days, depending on the carrier. Since the phone came out on the 19th, you should be good to go.
If they have what you in stock then you pay a $35 restocking fee to get the other phone. I am waiting for a gold one to come in to the same thing. I do not hate my space gray 6 Plus, but would rather have a white faced phone this time around
