First you have to login with your user name and password.

Then go to the appropriate country and find your listing.

ONLY in your entry will appear 2 buttons "EDIT' and "DELETE" over the companies title, like the image below.

By clicking "Edit" you have the possibility to change and update your listing.

With "Delete" you remove your listing. Be careful. If you press delete by accident you will have to add your listing from the start.
