Duolingo's promotion code didn't apply, how can I fix this?

If Duolingo's promotion code did not work, start by examining the terms and conditions.

Check that it was entered correctly, has not expired, and satisfies any eligibility conditions, such as certain subscription kinds or areas.

These details are available in Duolingo's Help Center (https://support.duolingo.com/hc/en-us).

Next, collect any relevant proof, such as a screenshot of the code, error messages, and your payment confirmation. Contact Duolingo's support team via their Help Center (https://help.duolingo.com/hc/en-us) or email **[email protected]** and describe the problem.

Provide any supporting evidence and request a refund for the discount or the coupon to be applied to your account.

If the problem persists, you can escalate the situation by filing a complaint on Xolvie to raise awareness about the issue and inform others.
