I had the same experience but i didn't have a pop up, just noticed on a credit card statement that I use frequently and for once just had one charge on it for Northstyle VIP. Called them and ask what it was.
At that point they told me what I had signed up for. I bought a sweater eleven months ago for a Christmas present for myself. Nothing else since. I have been charged for the last eleven months for some VIP membership I had no clue signing up for.
I should of monitored my charges more closely, I know.
The point being after talking to them they will refund the last ninety days but nothing else. Time to file a complaint to the BBB and FTC.
