NO REFUND AFTER 1 MONTH

HOW HARD IS IT TO PROCESS A REFUND FOR AN INCORRECTLY DELIVERED ITEM. I ORDERED 2 ITEMS, WAS DELIVERED THE INCORRECT ITEM, I THEN REQUESTED A COLLECTION AND REFUND. ITS BEEN ALMOST A MONTH NOW AND STILL HAVE NOT RECEIVED THE CORRECT REFUND AMOUNT. I HAVE BEEN CALLING AND EMAILING AND NO ONE SEEMS TO KNOW WHAT THEY ARE DOING. REFUND ME FOR THE INCORRECT ITEMS DELIVERED.
