why not just ask them to stop calling?

Who owns this phone number?

They are persistent.  Numerous calls asking to speak to my spouse.  They just keep calling.  Call display indicates Health Tek Enterprises.

I just got a call from this number but I missed it. By reading the below messages written by people, I safely assume that this is a scam. I won't answer the call from this number in future. Thank you.

beyond annoying not sure how they got my number and would very much like to get them to stop

You have to tell them to remove you from their calling list.  If you just say "dont call me"it won't work.
