Zandu — Zandu honey

I bought zandu honey in amazon.I regularly buy zandu honey and daily consume with food.I bought it from amazon last saturday, opened and tasted it .It is bitter and creates itching on the tongue.I tried it later 2 to 3 times, the smell and taste is like spoiled honey and there is same itching on the tongue.I request the zandu company to refund me..for this adultered honey.
