If the Oscars had a "double standard" acting award. He would have won.

He won't believe any of the Fact checks and explanations you make. He will question why you should trust the data you have checked.
And he himself cannot provide any evidence to support his claims. At the same time, he would tell you that he is a genius and forces you to believe that everything he says is correct.
He chose the red product when he purchased it. We send out the red product. When he received it, he furiously questioned us, saying why we sent him red one when he bought white one.
We told him that we had check and he had selected red when he placed order.
He started his show and told us that we cannot just said it was the buyer's fault. (We didn't understand, we didn'tblame him anything, we just told him after checking the data the fact was that he bought the red product)
Then he started to get hysterical and said that any data we checked must be inaccurate and the data was unreliable. We shouldn't trust Amazon's data. He insisted that he had purchased a white product when he placed the order. And forced us to believe only what he said, not the data. And said he couldn't stand to be insulted.
When we asked him to show us proof of his claim, he refused to provide it.
(Again, we could not understand. He was unable to provide any proof to support what he said from the beginning to the end. Everything is just his word. Instead he asked us not to believe the data, but only what he said. If he did choose white when he placed the order, he could have provided a screenshot of his side of the order to refute us. But he wouldn't provide it, and we just calmly told him the facts without being rude or insulting to him verbally. but he enacted the role of the victim)

Is it so hard to admit that your memory is wrong? In the absence of any evidence that your memory is correct, do you think we should trust your subjective memory, over more reliable and objective data?
