Sounds horrible. Mobile phones are bad enough, I don't want any more 'guaranteed' ways to be contacted by work or other annoyances in my free time.
You are just lucky with your number. We get an average of 10 calls a day. Yes, in France. Stuff like Bloctel do not work, it isn't respected. I don't even know if fake caller numbers are now finally disallowed, it doesn't look so; anyway they were allowed for a long time.
Each time the government grants subsidies for whatever, it is immediately diverted by an enormous amount of companies which deal with the grey areas of the laws (laws concerning that subsidies and laws concerning solicitations), and if you have a residential number, you get spammed with commercial robot calls all the time (and then there are the 'empty' robot calls, too).
