Every spam call I get is from a different "burner" number
Its probably not. Most probably the number is spoofed.
In either case, there is not much you can do. In New Zealand, there is a Government organisation, that you report this to. But again, theres not much they can do, except to put it into a database.
I think its highly improbable that the same number will be used by a genuine caller in the future. These numbers are often not valid. The ones I see are too long. So you can block them, but there is no benefit to it.
In short, don't stress and ignore it. If I can't recognise a number and I am not expecting a call, I usually don't answer. If its genuine, they will either leave a message or call again.
Most of the spammers have it automated. The computer calls random numbers or from a list purchased on the dark web. If you answer, it gets transferred to a person. And now they know its a valid number. It then gets added to a list.
