Due to damaged telephone wires after a flash flood in Northrhine-Westphalia, our employees at the Velbert and Wülfrath offices are only partially available at the moment. We apologize for any inconvenience. Together with our phone provider we are working hard to fix this problem. An emergency call line has been set up. Due to the reduced capacity, we cannot make sure that all the calls will be answered. Feel free to leave a message on the answering machine. We will call you back as soon as possible. Our colleagues are also available by e-mail as usually .
