The FDZ of the BA at the IAB was accredited by RatSWD.
In July 2016 the RatSWD opened a complaints office, which will give you the opportunity to address unresolved problems with the usage of the FDZ data that you cannot solve together with the contact person at the FDZ. The contact form as well as details on the field of competence and the procedure can be found on the website of RatSWD.
