Disappointing

Such a disappointing experience. Ordered 5 bottles of green tea gum and 1 bottle of spearmint. A week later I was emailed to say they don’t have spearmint, can they send another flavour. I say sure. Then they reply and say they don’t have that flavour can they send another. I say fine. No other word or tracking number. Parcel arrives with 5 bottles of cinnamon gum. Recalling I ordered 6 bottles of completely different flavours. I email to tell them I cannot use cinnamon gum and would like them to collect the gums and give me a refund. Zero response.
