On the second order, I called after two hours to ask and add one more item, just one, and the person in charge of our orders in Playmobil Hellas said ''this time its ok, but please be sure what you need of next time and place it all together with no alterations, or wait and put this item in your next order, because the office in Germany,'' (from where all our orders are beign processed, packed and send to us) ''got furious as they had to process the whole order form from the beginning for just one extra item.''
There must be an exceptional matter of lightspeed involved with the way DS-Greece works, IHMO.

Here in Belgium (and I think with most european DS-services, except Germany itself), once one has emailed/faxed/posted his or her parts-order, it takes some time (usually 1 or 2 days at least) before one's order is processed at the local DS (depending if there are weekends or not, busy times or not, etc).
The local DS-department is linked to the database-system in Germany, and they first check availability of the parts one has ordered. If some parts are unavailable, usually the local DS-department will contact the person placing the order about this by phone or email. When they do so, one has f.e. the chance to add some parts instead of the unavailable ones.
Then the local DS-departement forwards the order to the main DS-department in Germany. Once the order is processed there, making changes is no longer possible. But usually you get enough time in between to make a few alterations. Off course, it is not very recommendable to do so.
