You may be able to reverse search the number and find out the provider then reach out to them and report him, hopefully that will hinder him from getting burner numbers easily.
for some reason telecoms worldwide are allowing voip companies to spoof almost any number - you can ID them but require cooperation of too many companies for a single individual without a court warrant
IMO he is spoofing numbers so he can set anything as a call ID anyway.
I was called by spoofers for a few weeks (same exact time every day but with a different number). My (European) provider said they can’t do anything about it.
Truthfully nobody is safe on our current phone system.
Even though this is not probably what is happening to OP and I don’t want to overly worry them but checkout this video by Veritasium :

Trivial for law enforcement, almost impossible for regular people
Depends if you’re in a country where ID has to be shown and registered in a database when activating a SIM card.
It is likely a voip that is being used.

Maybe OP should change completely of phone number.
