Called. Received a friendly woman on the phone. Since I was 4 km away, she told me to come, ring the bell or honk the horn. Did all that. No one to see. Called the lady again. Didn't answer. Then I drove to St. Pola, 10 km further, and was able to discharge cassette there for €2. A bit of a farce with Chris Aupa. Apparently you have to be lucky.
