Please cancel my account and organise a refund on all my money (total GBP331.80) back. I found the product is not working on me at all.

I registered for a free trail on 14 April 2009 for both Acai Berry Detox and Life Cleanser. I received these items on the 10th and 13th days after the order and I was charged USD11.86 (USD5.93 x 2) as shipping cost by 2 different companies (Vitalityclean and Natureberry). After 2 weeks trying on these products, I found they don't work on me and I'm not intended to place any order at all after the trail order.

Last Friday 9 October 2009 (which is 2 months after I placed my trail order), I received another bottle of Acai Berry Detox which I have never order for. I then checked my Visa card and found a total of 8 transactions (including 4 overseas transaction fee) in the amount of AUD563.70 have been debited.

On 12 October 2009 Monday, I called Health Scicence on their Int. Tel +44 203 139 9104 to organise money refund and product return and I experience and very rude customer services. He shout at me over the phone about the "15 days account cancel to avoid debit for trail product and automatically monthly subscription for the product...etc ". He also specified that all these things are listed in the term and conditions of purchase. Eventually, he told me someone will be in touch with me in email to organise the refund and return.

Here comes the issues:
I ordered the products through a suggestion of a blog showing how good the products works and the 30 days money back gurantee promise. However, I'm 100% sure nothing on the webstie presenting anything regarding the 15 days trial and account cancellation detials.

Until yesterday, my first trail order is due for the 30 days money back gurantee but I haven't received any written confirmation about my request of return and refund. After reading all these complaints of the company, I really worry about if I can have my money back.
