Always hangs up; never leaves a message

Call to help with credit card debt.  I have no such debt. Numerous calls daily.

How many "final courtesy" calls can I get?  Perhaps one of us does not fully understand the definition of the words "final", nor "courtesy".  It would be a marvelous courtesy for these fools to FINALly stop calling!  I've gotten to the point that I just waste their time for about 10 minutes by speaking with some sort of accent and acting as if I cannot understand everything he or she says (but still enough to keep them hooked); or acting as if I am elderly and senile, searching for paperwork, etc.  After about 10-15 minutes, I will straighten up and tell them - "Just thought I'd let you know what it feels like to have your time wasted - Take me off your list and Have a nice day"  Sadly, they usually hang up before I get to the last part.  HA!

They call here 3 or 4 times a week.  When I do get a human to complain they hang up before I finish my sentence.

Received many computer generated calls from this number, even twice per day.
