"John" or "Mr. Montgomery"
It is not may debt. I've gone through the rigamarole with them once and it's someone else who gave them our number.
They ask my name and phone number, which I refuse to give since they called me.
I ask for a supervisor and the horribly rude man - immediately hostile and rude, and I believe the same man for both calls - told me "This call is being terminated."
Incredibly bad system - they call me, then expect me to give information.
