Who has used the edible fungus products of Hefei Han Qi Biotechnology Co., Ltd.? What's the effect?

Please be patient with my experience if you don't believe me. Just last week, I was angry.

This product is not allowed. I just had a quarrel with a salesman named Shi a week ago. The thing is this: my mother has high blood pressure and bought this set for more than two thousand yuan. I looked it up online with "I check", and it only cost 1000 yuan, and then I called the person who sold my product. That person said that the online quotation was wrong, and then my invoice was in other places, not in Hefei. I really thought it was a big joke when I heard it. You set up factories and companies in Hefei. Don't you have to pay taxes in Hefei? In addition, no matter which city you sell medicine in, you must give the invoice to the seller. Ok, no, I asked them to give me a receipt, but they didn't open it either. Later, I said that if you didn't give it to me, I would complain. They came to my house soon and brought one. At that time, my mother was too proud to say anything, and then I said, if I don't say anything else, I want an invoice. I bought your products and such expensive things (just three boxes of more than two thousand), and then he said yes, and I said next time. (I didn't respond later. )

When I went home again, my mother bought it three times, nearly 7 thousand. It happened that he called me. He got angry on the spot when I asked him for a ticket. I said, I just asked for a receipt. Why don't you give it to me? Otherwise, you should give it to me. Whether it's shopping in the supermarket or taking a taxi, buying electrical appliances or eating in a restaurant, others will. Then you want to get well, just keep eating, forget it, and then "pa", hang up my phone, and then after a while, the middleman who works as a lobbyist came to my house again and told me that there was no receipt or something, and then told my mother that it was useless for you to issue an invoice. Finally, when you left, you said, you still don't want to buy this. let us

The day after I came back to work, I checked it again with "I check". The price on it was gone, and the online price had been changed to five or six hundred (it was their own website).

Up to now, I don't know why he didn't give me the invoice, because they evaded taxes informally, or because they overcharged my mother 800 yuan (the total price of three boxes was 2,000 yuan, which was a fraction, but I found it was 1000 yuan, even a fraction). My mother has eaten three courses, and it's still the same. Do you think they are credible? If someone buys it again and someone believes it, you'd better ask them for a formal invoice when you buy it. There is at least a small guarantee if there is an invoice.

(Attachment: If it is bought by the elderly at home, be sure to pay attention. They often call every three to five days. Uncle and aunt are so sweet, ask what's going on. If they think it's okay, say it's medicinal. If they feel dizzy, they say the medicine has worked. It will be all right in a couple of days. Damn, hypertension is always dizzy and uncomfortable for a few days. It's generally good, it's good. It is recommended to listen to the doctor's advice more, and don't believe that these small pharmaceutical factories, synthesized with some mushrooms and other things, have become magical drugs. And I looked it up online and found that they can cure high blood pressure and stomach trouble. Anyway, they treat everything, but they always give you six kinds of health care drugs instead. You can check more if you don't believe me. )
