Are all online pharmacies selling real medicines?

It is hard to say whether it is true or not, but their attitude is really like a chameleon. When you need to buy medicine, you call again and again, and your tone is particularly good. You also said that you could call them at any time, but after placing the order, you said that it was temporarily out of stock and it would take a few days. When I offered a refund, I went away, either asking for leave or having a meeting. The tone was so bad that people wanted to scold their father. As for the refund, they said it would take at least a week.
