[Dx-qsl] 5N2/SQ8JCA - any luck, anyone?

[G. E. Janssens - K5WW]

Hi all,
 
I worked Marek 5N2/SQ8JCA way back in 2007 for my only 20 m phone QSO with Nigeria, so far. The online log shows that I'm in there, no problem.
 
But repeated direct QSL requests to Marek have been unanswered so far. No replies to my bureau requests either.
 
Worse: several emails to the email address listed on QRZ.com to Marek have yet to be answered. Some of them were as recent as this year.
 
Has anyone here ever received a QSL from SQ8JCA? Or an email reply, for that matter? Is there someone in the Polish DX community who knows what happened, maybe?

Thanks for your help. 73,
