I did pick up the call that claims it was a collection agencies. Knowing this couldnt be correct since sadly I have a chart of all bills and all have been received and paid, I called back to let them know they have a wrong number in hopes not to get repeat calls. After being on hold for 15 minutes I hung up.

They keep calling with a recorded message, telling ME to call them back, but on the message, don't tell me what it is regarding. I will not call them back.
