I ordered some scents from NG this last month to replenish my stock. When I did it, there was a sale going on where I could get an additional rewards for orders. However, even after I placed my order and received the selection, they hadn't increased those rewards even for what I had bought.
I contacted their customer service a time or two, NG apologized and said that they would take care of things. When I finally got my additional rewards a few weeks later after the contact with them, it was only increased by 17 even after all that trouble. Needless to say, I'm still not impressed...
