Ripp off

Two weeks ago i bought a pair of adidas at the Worcester branch while on holiday. So when i get home.. earger to wear my shoes. Im like no man this dnt feel right. Bt my husand and i still say its probably cause this is the shoe that every one tried on. So when i do check..its a size and 6.. I go to my nearest store. And they advised thy cant chabge it cause if its the last stock the store do sell it to pple likr tht. And im like no man. That guy told me ntn.. and it not even comfortable walking like tht. I would have never taken the shoes if i was told tht.
