They advertise on Facebook as Young Vibes, Your Child Freedom Formula, Peaky Parents, Anxiety, Our Formula, and various other names.
They use a 'high ticket' sales technique, where they offer a webinar and then urge you to book a call. The call is a high-pressure sales call.
They have changed their name quite a few times over the last year, after they were investigated by the Advertising Standards agency - www.asa.org.uk/rulings/tomwill--holdings--ltd-g21-1116080-tomwill--holdings--ltd.html, and they were featured in a BBC radio 4 documentary www.bbc.co.uk/programmes/m000zt9y
There are a few threads on the child mental health boards - here's one. www.mumsnet.com/talk/child_adolescent_mental_health/4239684-your-child-freedom-formula-has-anyone-tried-it?page=1
On the threads there are people from 'both sides', including some who have been through the program, so it's well worth having a read if you are thinking of making the call.
