I too have been scammed by Viv 3 with the purchase of the free trial of Acai Berry & Life Cleanse. I did not see the small print in the terms and conditions which state that if you do not cancel within 15 days of ordering (not receipt) of the "free trial" then you will be charged the full price for the product and also entered into a monthly subscription. I only found this out when I checked my credit card statement. I have never received any products from them, not even the free trial.
I spoke with my credit card company who advise that it is best to contact the scammers in writing, I emailed them and got a standard reply to say they don't respond to emails. I called them yesterday and was advised they would put my request for a refund forward. I have today been advised (by email) by them that I will not receive a refund.
I have spoken with the disputes department of my credit card company and they will now take the matter forward as I have been charged for goods and services I have not received. It may be that it is the credit card company that refunds me my money (nearly £300) and not the scammers, but at least I have a chance of getting my money back.
My advice to you is, if you have just ordered, phone them and cancel and ask for a confirmation in writing and a confirmation number. Advise your credit card company/bank of the issue. If all else fails seek the help of your credit card company or bank as I doubt that Viv3 that will refund monies.
The credit card company advised me that as I can prove that I tried to contact them and that I have requested they cancel any subscription if they now try to take any further monies they can be charged with fraud.
The credit card company also advised that it is better if you have not received any goods as you can be refunded by them in due course for not having received goods or services - therefore when the postman comes, do not answer the door and do not take in the products.
Failing that, lets all get together and pay them a visit...
