Alarming phone call from Mamela Consulting

I'm extremely concerned by a recent phone call I received from Mamela Consulting. They contacted me out of the blue, claiming to have information about my financial situation. However, The details they provided were completely incorrect.

I'm shocked and worried about how they obtained my contact information, as well as personal information (My ID number). Where did they get it from? It's unacceptable and raises serious concerns about data protection and privacy.

I would like to report this incident, but I'm not sure where to start.
