I believe Vyjak is based in China and is very dodgy. I was not happy with the goods I ordered, not onlyb because they looked dreadful on me but especially as I believed I was paying in Australian dollars until it was too late. The amount deducted was in American dollars (a $70.00AU difference).
Vyjak Store at vyjak.com

The goods were not as described from the outset. Someone in the company tried very hard to persuade me to take a partial refund, which went up in increments as I insisted on a full refund, until I contacted PayPal, who succeeded in obtaining a full refund.
I was asked to return the goods to America and then China, even though there was an Australian address on the package. Fortunately, PayPal gave me a voucher to the value of the postage ($35.00AU)... Lesson learnt.
