EDIT: Title was cut short...
"According to the FTC, some of Zurixx’s unsatisfied customers have tried
to obtain a refund from the company, but the company allegedly required
some consumers who received a refund to sign an agreement barring them
from speaking with the FTC, state attorneys general and other
regulators; submitting complaints to the Better Business Bureau; or
posting negative reviews about Zurixx."
Honestly, I feel bad for people put in this situation. I'm sure that in the heat of the moment the special* exclusive* offers that gurus offer are very enticing. Some people watch them for a long time on tv and build trust even when they don't actually know them.
