This is **very likely a scam** (also called "smishing"). Here are the clear red flags:

🔴 **Fake URL:** The link goes to `dhl.com-redelivery.eu` — this is **not** an official DHL domain. Real DHL communications use `dhl.com` or verified official regional domains (e.g., `dhl.de`, `dhl.co.uk`). The path `/p/8KX2Q` is also generic and easily spoofed.

🔴 **Pressure tactic:** "Pay within 24 hours or it will be returned" is designed to make you act quickly without thinking.

🔴 **Unusual amount:** Customs fees are rarely exactly `1.99 EUR`, and DHL doesn't typically demand immediate payment via an unsolicited SMS link.

🔴 **No shipment details:** Legitimate DHL texts include your name, a tracking number, and specific delivery info. This message has none.

🔴 **Payment via link:** DHL never asks you to pay customs or redelivery fees by clicking a link in a text. Fees are handled through your local customs authority or DHL's official payment portal (which you reach by logging into your account or using a tracking number on `dhl.com`).

**What to do:**
- ✅ **Do not click the link** and **do not enter any payment info**.
- ✅ **Block the number** on your phone.
- ✅ **Report it:** Forward the text to `phishing@dhl.com` (DHL's official phishing reporting address) or use their online scam reporting form.
- ✅ If you have a real parcel, check its status directly on `dhl.com` using your tracking number (from your order confirmation or seller, not from this text).
- ✅ If you already clicked the link and entered any info, monitor your bank/card statements and contact your bank immediately.

Bottom line: delete the text, block the sender, and ignore it. DHL (and most major couriers) do not operate this way.
