Year 2020: 40k complaints about 18k phone numbers (12% from outside Germany) for predictive dialing. 155k complaints about phone spam (company trying to sell you something). 1.3 million Euros in fines. https://www.bundesnetzagentur.de/DE/Vportal/AnfragenBeschwer...
I received one spam call in 2020.
