Unfortunately I don't know any number for Samsung in the EU or I would give it to you. You could do a local web search for "Samsung telephone" and look in what you have for telephone directories. At least you would get a dealer who could get you in contact with the regional sales manager.

The regional sales manager usually refers end users as yourself to local installers to service your system. As your only problem is that someone changed your password without your authorization, your RSM may help you out with Samsung or refer you to a local dealer.

If I were a local dealer I would jump at the chance to give you a "freebie" on this help with the hope that you would want to call on me for future needs. Others would see it as a chance to charge you for a full service call. If the RSM gives you multiple installers you can call around and see who is the most helpful.
