They have been calling me dozens of times and I finally answered the phone and they said that I had a balance due on my cell phone account.  I have never heard of them and they were calling me on my work cell phone.  I don't pay that bill! I asked my employer if they knew who they were and they didn't know either...

I called them back, it was Cellular One calling me about my bill.

who dat??

wish they'd stop calling

same.  answered right away but they hung up.
