Problem gelöst – mein Name wurde entfernt.
I received a nice email from Kelly Search apologizing for the delay and saying they had removed my details from their website.
As I said in the comments, after I had posted on this topic, I had a vague sense of déjà vu – I think my details were originally taken by an offshoot of Kelly Search in an Asian language using the Roman alphabet. They had me down as a seller of tables and curtains. But my communication with them was hampered by misspelling.
So all is well – unless I suddenly see a more interesting future in selling tables and curtains and have to kick myself.
