I redeemed a voucher but was still charged money. Why?

Don't worry, there is usually a simple explanation. Please check two things:

1. Is it a hold/authorization? Especially with mobility partners (e.g. Lime, DEER), it is often just a temporary security hold (authorization). The provider reserves a small amount to verify your payment method before applying the credit. This hold is usually automatically canceled after a few days.
2. Check the final invoice: Please always look at the final invoice or statement from the partner (not just the hold shown in your banking app). The voucher should be correctly applied there.

If the discount is actually missing from the final invoice, please contact the partner's support directly (e.g. Zalando, Lime, etc.), as they are responsible for billing.
