Have started calling multiple times every day.  "This is Ashley calling about your credit card account".   I have waited to speak to an operator, the first thing out of their mouths is "do you owe $2000 or more in credit card debt".  When I try to say anything at all (like do not call here again), they hang up instantly.  Pressing the number to be removed from their call list is also ineffective.  Is there some way I can prevent this?
