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 :
