If I were you I would return it and ask seller to refund, if you don't like it, it's absolutely no point to keep it. Trust me, in many cases seller much prefer to refund or even pay a bit of extra to on return cost instead of getting a neutral or neg, as you return the item you are not doing seller a favor, you're getting yourself a fair deal.

BTW a neutral or negative FB can't solve you any problems, perhaps it doesn't even makes you feel better after all.
