another disease in the long list of telespamming diseases.

Why are the phone companies not blocking these telespamming vermin?

Phone companies are "common carriers".

That means they must allow everybody to use their services, unless the company is notified by law enforcement that the user is committing crimes.

So, the phone company cannot universally block a number merely because YOU complain ... however, they might give you the ability to block those calls to YOUR phone.  Even better, you can protect yourself, by using a call blocking phone, app or other device.

Do not depend on others to enforce rules or policies YOU invent!  Protect yourself!
