I bought the ETS brand and was surprised it had a black pepper taste, not sweet and spicy like every other chai I've ever had. I reported this to customer service and got NO REPLY. Very disappointed in their product and customer support.
Not easy. Once the order is submitted it is hard to cancel or modify. However they get in touch with you if something you ordered is not in stock. They usually ask if you want a refund or delayed delivery in a separate box at their expense.
