It didn't work for me so I deleted the app but they kept taking my money. It's almost impossible to cancel. Once they have their hands on your account they just keep taking. BEWARE!!!! I have now cancelled the PayPal subscription. Maybe when they can't get anymore money they will reply to the many messages I have sent.

Ok as requested, I have now sent a 7th message to the so called help line. I had already sent my email details as they say. Of course having deleted my account no other information. Let's see if I get a reply.
June 21- I wrote as instructed on the date of their reply and have heard nothing. Who wants to bet I hear nothing until they try to access my PayPal account and find they can't. Then try to make out that I am at fault. You would think at least a courtesy email might be in order after this review (I usually give good reviews) but no. Nothing.
A week later and no reply. Make up your own diets. This is a hussle. Subscription date is nearly here. Lets see how far they will take it.
July 2 still no reply or cancellation confirmation. I continue to send messages.
July 27- To end this, I never got a reply except on here. No offer to make amends. They also didn't attempt to dispute my turning off PayPal subscription. Just took my 90 pound over payment and slinked off into cyber space. Avoid this company. What they offer can be replicated at home. They are just after the money of vulnerable people. Beware.
