Moral of the story that I am hoping you take: psychics are deceptive, untrustworthy people.
My aunt became addicted to a psychic who bled her out of tens of thousands of dollars over time. She would lie about being able to hear messages from my deceased grandfather, which I have to imagine she did by just giving vague suggestions, because grandpapa did not speak English.
It even got to the point where we had to stop her from donating huge amounts to the psychic after she'd come up with sob stories about having to leave because she had to go take care of her son across the country who couldn't pay rent, or her sister in Chile who was going to lose her business. It was a long battle for my cousin to get a conservatorship over her accounts and cut her off.
Basically, psychics don't want customers who might have doubts about them, hence why they decided to turn you away. They don't want you to give any of their other marks the impression that it's all a scam.
