All applicants are strongly advised to not deal with any agents.

The Embassy only cooperates with VFS Global. The Embassy has nothing to do with sellers outside the premises of the Embassy or the VFS Global office, or other agencies or persons approaching applicants in order to offer services. No agencies can influence the processing time or the decision in any way. If any visa agents say that they can influence your application, we urge you to immediately inform the Embassy.  

Also note that even if an agent has filled in the form, you are personally responsible for all information and documents that you hand in with your application.
