Appear to be a debt collector but are asking for someone who isn't me

Receive calls from this number several times a day.  They are looking for someone who does not live at my address. Have asked that my number be removed but they refuse.

They say they are Whole State Financial Services. Asking for someone that doesn't exist here. Told them I would be happy to take their calls everyday and I would send them an invoice for my time.

Have told them over, and OVER, and OVER AGAIN, that this is my new cell phone number and I am NOT that person, but they continue to call every damn day. They need to STOP calling me.

some one from this number keeps calling my cell
please stop
