It may be cheating but trusting blindly someone without doing your own due diligence, is that stupid ?

I paid the money. Everything they said was money. Yesterday the CEO was a jerk. He told me that if you pay the last 7000 rupees, you will get the money in 30 minutes. Now they say that you have to pay $500. This is not a scam. This is not a fraud company. Isn't this cheating people? What they are doing
