Umpire's decision 'unacceptable', why Preity Zinta got angry

Preity Zinta got angry again. A few days ago, this Bollywood actress and Punjab Kings owner was angry after a picture of her fake hug with Rajasthan batsman Vaibhav Suryavanshi was published. This time, Preity is angry with the third umpire. She is angry about a decision in the Punjab vs Delhi match yesterday.
What is the real incident

The incident happened on the last ball of the 15th over of the Punjab innings. Shashank Singh hit the ball towards long on from Mohit Sharma. Karun Nair was fielding there. Nair stood on one leg very close to the boundary and caught the ball and hit it into the boundary. However, after doing so, he immediately pointed for a six. This means that his foot hit the boundary rope. At least that's what Nair said.

However, the third umpire saw something different in the replay. He felt that Nair's foot did not touch the boundary rope while holding the ball. The fielder signaled for a six, but the third umpire did not give a six. On the other hand, batsmen Shashank King and Shreyas Iyer ran late, thinking it was a six, and took 1 run.

That's what got Preity Zinta angry. The Bollywood actress also spoke to Nair. After the match, Nair told her that it was a six. Preeti expressed her anger on the X, "In such a big tournament, where the third umpire has so much technology, such a mistake is unacceptable and should not happen at all. After the match, I spoke to Karun and he confirmed that it was definitely a six."

In a T20 match, every run becomes very important. Delhi reached the target of 207 runs set by Punjab with 3 balls to spare. If that ball had been hit with a six, Punjab would have scored 211. The result could have been different then. Iyer and Shashank did not take more than 1 run in the run because of the sixes, where 2 more runs could have been taken. This is why Punjab owner Preeti is angry.
