Order #2289921NA

Hello, I was told me exchange was approved. Given a code to use to cover free shipping to purchase and send in the bathing suit but that code didn't work & now I've been getting ghosted. This has been an extremely frustrating experience as returns and exchanges have windows and time frames on them and my first experience with this company. I would like to get this sorted as soon as possible. Please send me my return label to send in the old bathing suit and send me the code the will waive shipping fees so that I can get the bathing suit in the style before it completely sells out. I want to get an XL in too and XL in bottom.
