so it wasn't just me... i ended up cancelling.
Mine just arrived today but..... They got my order wrong :( . Just checked the account and the next order also comes up as 0.00 so I will still keep my subscription up.
just emailed support and my bars arrive today or tomorrow but my sub says next batch feb " bi monthly" and there also free and apparently the deal is for 3 free orders of 6, so original deal of 18 that got changed to 6 was right as its 6 x 3 orders.... will await and see if the bars are ok and if its worth waiting another 2 months for free 6 or just cancel now.
Bars arrived and they were vile. Urgh.
I had a £0 charge, 1 day later another charge for £22... brilliant!
