Refund rejection without reason

I am deeply disappointed in Reebok. I bought 4 pairs of shoes and a shirt online. One pair of shoes and the shirt was on a 2 for 1 offer, but the only sent 1 item of each.

I then tried on the shoes and decided on the right fit and comfort and sent the other pairs back.

Much to my surprise the one pair of shoes was rejected. I have photos of these shoes, there is NOTHING wrong with them. I never wore them, tried them on once. The labels are in tack, the soles are perfect. I even took them to a Reebok outlet and the manager couldn’t understand why they rejected the refund.

My biggest issue is the fact that I can’t appeal the decision or escalate the matter. They are basically saying, accept it! Whether they are wrong or not.

I now have 2 pairs of Reebok shoes, one pair that I didn’t want to start with, and another that I don’t want because of the bitter taste this company has left me with.

I have no idea how to get this resolved. Must I just simply accept it?!?
