I don't think so, I've had friends and acquaintances that had the same issue as you, multiple spam calls per day. I helped them add themselves to their national list, and after a month or two the constant spamming stops.

I think you might just be unlucky living in country that doesn't have such list that works OK. I've lived in multiple different countries so far in my life, and it's been the same thing in all of them, adding myself to the list eventually makes the spam stop.
