336-903-6705-once at home, then at work...any ideas?

2 calls, both on my cell phone. They don't leave messages. Annoyed!

This is a collection agency.  They called on a Sunday morning & were harassing my wife about someone we didn't know.  Advised them that we had the phone number only 3 days, yet lady kept being persistent.  I told her to remove our phone number from list, she just kept going on and on.  I advised her I was recording our phone call and would be reporting her.  She told me I didn't have her permission, but I advised her that since I'm in Texas, I don't need her permission, nor do I even need to notify her.  She immediately said that she was taking our phone number off of the list.  End of call.
