Ingredients to die for reviews and complaints

I had been a loyal customer of Ingredients to Die For since 2010 and I have been patient with them through many mishaps. However due to rudeness, and unethical practices I have placed very few orders unless I am in needing something that I can't get somewhere else. But apparently they have flagged my account because of a complaint I made previously. A few months ago I placed an order for essential oils based on their claim to have "therapeutic grade" essential oils. When I received the oil that I ordered I immediately got a headache when inhaling it and I asked for proof of there therapeutic grade claims. They said that it is too expensive to test oils and they could not show any lab tests that their essential oils were therapeutic grade and I had to just trust them. How can a company even know if their oils are therapeutic grade without testing? I decided I wouldn't order from them again. I was in a pinch when I was staying in Austin and needed to place a quick order of ingredients outside of essential oils to pick up. After a full week I still had not received a pick up confirmation and when I checked my account it said my order was cancelled. However my bank account showed that a charge was made to the account. I sent an email asking if there was a mistake made and they sent a response saying they cancelled my order because I didn't agree with their policies the last time I placed an order. Really? They aren't allowing me to order from them because I don't agree that they should make scientific claims without the evidence to back them up? And more importantly they didn't send me a refund or let me know that they were cancelling my order. I have never seen such unethical business practices like this before. It's unbelievable.
