Players eliminated in the second round of the men’s singles receive 130,000 euros ($151,000 or £112,000) in prize money.
After organisers said they would fine Vallejo on Friday, the world number 71 apologised on social media.
“I have respect for the umpires and for the job they do, after a five-hour battle I was very heated and felt a lot of emotions, I apologise,” Vallejo posted on Instagram.
According to the Grand Slam rulebook, Vallejo could have received a fine of up to $100,000 (£74,200) for unsportsmanlike conduct.
