Hey there , hope you guys all doing well ,
This is my first post hope I'm not posting in wrong section,
It's regarding to find someone in Cologne , whom my father met in 1980, I have his old business card and his address,tried a lot of online telephone directory but couldn't find them ,is there any other way to find?
I have his old telephone number, but obviously it might has change.....
By the way I'm not in cologne right now , I was there last year , I tried to find that time , but because of time I couldn't, might I'll be visiting Germany again next month, if there is any other way , Please do let me know.
