2. So according to the above tracking your parcel is On Route to Croatia. Now it's up to Croatia Post to scan your parcel to get it to the Croatia Customs Office for clearance.

3. According to the above tracking, your parcel is fine, you just need to wait for it and track it on the Croatia Post site for any new movement.

4. If by the 10 Nov you have not receive your parcel contact seller to tell him. If he does not respond, then open a dispute for not receiving your parcel to get your money back.

Hope this help.
