I am glad i have never ordered from Black Jungle, but i have had a similar experience that turned out well with Wistuba
It was way back when i was ordering my first helis, i bought the basic pack of H. monor, H. nutans, and H. heterodoxa
Unfortunately they accidentally sent me the 5 random nepenthes hybrids pack instead
I contacted them and they promptly sent me my replacement plants WITHOUT asking me to send back the neps
In the end i got my helis and 5 free neps
Now THATS good service, why can't everyone be like that
