Unclear App on 1st 50% Off Purchase – thredUP: Online Thrift Store Review

On my first purchase I used the 50% off Code and did not apply for the items. Then talking with Customer Service they said even if the discount didn’t apply, but used, and could not change the price. The Code was voided and could’ve used again for a actual purchase where it could apply. The app should say under Coupon not to use the Code if it didn’t apply or change the final purchase price. Very disappointed with Customer Service.
