I didn't answer but called back to see who it was from and got a message saying they are from Select Customer Services saying I recently did business with a sister company and if I want to get off their calling list I need to email dnc.scs@dellsouth.net and give my full name, number, address, and so on which only an idiot would do.

The only other unknown call I get from CA is from Time Warner Cable so they might be responsible.

The phone number recording gave email address dnc.scs@dellsouth.net to remove my number and this is what I get.
Also Mail address  Select Customer Service, 11655 Central Pkwy., suite 303, Jacksonville, FL  32224 to request removal from call list. I suspect this is bogus,also. I ordered an item from a tv info-mercial  and weeks later, I got this phone call asking if they could send me, for free, some zirconium earrings. I said no thanks and hung up.
