Here's what I did, after receiving two calls from them last Tuesday & two more on Wednesday, none of which left messages, at approximately 5:31pm CST, I called the number back.  I heard what turned out to be an automated message meant to sound like an actual person.  The message said hello, this is Chris Harris, I understand you have some messy payday loans, correct? So I played along. It was really weird, there were pauses & everything like a regular phone call.  

After a couple minutes he said he'd transfer me to a representative who could help me further & even kept me on the line by making sure I was still there, very strange.

The operator soon picked up the phone & repeated how she could assist me with my troubles.  I could hear the other telemarketers in the background.  I noticed that she did not have a foreign accent.

I politely said to her that her company solicted me, that my number is on the do not call list & to please make sure that I'm removed from their database.  And if I were to be contacted again I would file an official complaint.

She confirmed my phone number, apologized & then I ended the call.  No fuss no muss, no shouting, no rudeness.

The duration of the call was five minutes & ten seconds & well worth the effort to get a chance to request that they remove my number from the list.

I called back later that night just for giggles & got a different message this time saying that nobody is available to take my call & the call was disconnected.

It's been five days now & I haven't heard a peep, so I think I'm in the clear.

Good luck everyone, don't despair, just be persistent to get to a live person & it'll work out.
