I admit, the person, contacted the Polish licensing authorities was in fact me. I contacted them when I didn't find any records about the 3Z9JK license in their online system. It was suspicious for me seeing the name, address, power, and callsign in different font color on the copy of Joanna's license, than the license number itself.
