I got involved with this group of companies in much the same way as Grumpy Customer (5.Feb.2015).
The first I knew of it was a 'pop-up' thank you for ordering a free trial of some products.
Although I had not ordered anything, the products did look interesting
and as the only thing that I had to pay was postage, I went ahead, using my credit card for the postage.
The goods arrived and I thought no more of it until
I got my credit card bill, showing the postage on 15th July 2015 (which was as I expected).
However, on 31st July, I had been charged £97.95 by Henesai Ltd,
then on 3rd August £99.98 by Aka Marketing Ltd.
These are all part of the same group and in addition to those in the heading of this post,
there is also Gold-Serum.Com and there may be more.
My credit card account shows Gold-Serum as Istanbul,
Henesai as Prague
and Aka Marketing as Hertfordshire
(its registered office is a registration agent in Hitchin).
I have reported all this to my credit card company and they are investigating.
