I really hope you don't believe that. Pretty tough to argue with satellite data yielding the imagery here -
World of Change: Antarctic Ozone Hole : Feature Articles

Click the buttons at the bottom of the image corresponding to the years from 1979 to 2015. Records show the hole rapidly grew in size and depth until the mid-1990s, since then the area and depth have roughly stabilized.

"The global recognition of CFCs’ destructive potential led to the 1989 Montreal Protocol banning the production of ozone-depleting chemicals. Scientists estimate that about 80 percent of the chlorine (and bromine, which has a similar ozone-depleting effect) in the stratosphere over Antarctica today is from human, not natural, sources. Models suggest that the concentration of chlorine and other ozone-depleting substances in the stratosphere will not return to pre-1980 levels until the middle decades of this century. These same models predict that the Antarctic ozone layer will recover around 2040. On the other hand, because of the impact of greenhouse gas warming, the ozone layer over the tropics and mid-southern latitudes may not recover for more than a century, and perhaps not ever."
