Fanatics.com Refund fraud jacksonville florida

I placed an order with Fanatics 21-7556-3750. They sent item Oklahoma Sooners Gameday Couture Women's All About Stripes Tri-Blend Long Sleeve T-Shirt & Shorts Set - Heathered Charcoal. Upon araival it was not as described. I contacted customer service and was instructed to return and I would get a credit back to my card. Instead they attempted to issue an e gift card that was invalid. Since the first of February I have been trying to get this fixed. The company states that the store credit card cannot get the credit as they made an error on the ecard. I have an email from Fanatics that states I was to create a chargeback dispute as "refund not received" with Synchrony Bank Fancash card. Instead of assisting me with their error they are telling me it is the card and the card states it is the company. I want the refund of $47.01 as promised.
