If the fabrics do not match up, you should probably return it for a refund. Contact the seller once your sure you want to go that route. Allow them a chance to accept the return. If they continue to deflect, open a case as item not described and go through the appropriate steps to return / refund. Do not ship the item back on a verbal agreement, rather go through ebays return process to ensure all parties are aware.
