I also received this text message. I texted back for them to call with the intent to have my number removed from the call list. I got a call back from some "debt relief agency" who stated that they received my number from ANOTHER company! I'd love to know where these call lists originate and who's using them.

Just got one that read exactly the same. Did you have any luck?

I just had the same experience.  When I called the #, the recording said the mailbox belonging to "Scam Artist" is full.

Same deal.  I received the following text:

"Dear homeowner, is your mortgage payment too high? Our relief program can lower your high payments immediately. Would you like to learn more about this?"

Calling the number back, I got a "voicemailbox is full" message.

I got the text.  Calling back the voice mail box for "Scam Artist" (Yes, that's what their recorded name on their greeting said!) is full.  Nice.
