Yes, every huckster selling stuttering miracle cures offers the same thing. And desperate stutterers convince themselves they've had a breakthrough in fluency. And then a few months later, when they've psychologicaly adjusted to the novelty of their 'cure' and they're again stuttering just as bad as before. That random phone call thing has been around for literally decades. A common scam. Short term results that disappear. It's tragic that people are still falling for it. It's the same story told over and over again. Hucksters taking advantage of desperate people is horrible. Helping these people take advantage of desperate people is just as bad.
