2. As you can see both parcels are On Route/In Transit to your country Bulgaria. May I suggest you read this for your country:
http://track-chinapost.com/China_Post_Arrival_Time_Stat.php

3. May I suggest you contact seller and tell him you have not receive your parcel. Maybe Bulgaria Post is very busy now and they did not scan your parcel yet.

Hope this help.
