As I went back to the portal for another withdrawal attempt on my EON tokens, I have noticed that my first verification information was not there anymore and I will go through another verification which led me to think that the first verification procedure was only a test . That explains why I had an invalid EON address for my first withdrawal . The whole portal was still in test period and as of today it still is. Going to wait further .
Exscudo team spent too much time on test issues until now the exchange is not fully ready yet, i have never tried to withdraw Eon because i will wait until the exchange is fully ready in use.
