They call 30 or 40 times (usually 4 or 5 times a day) and disconnect before you can say anything.
When they FINALLY talk, it's to tell you that some "chiropractor" in "your area" wants to do "free screenings"...blah blah blah.
I'm sure those "free screenings" come with a HEFTY price tag...BUT...the good news is, it's all just noise, and the runners of this little parade obviously don't have google. We're in Austin, and thus far, the "chiropractors" have been in Abilene, Dallas, and Johnson City.
