Stealing photos and using is to advertise falsely

Rene Marais is using my image of makeup that I have done for an advert for botox. I reached out to her via messenger on Facebook and she did not respond, I then posted on Facebook about the situation and tagged her to which she responded "Renwe Marais Nee dit is nie make up nie iemand het die foto vir my gestuur en ek het nie geweet dit behoort aan jou nie adv gaan oor Botox" she refuses to delete my image. I have on a voice note as well as on WhatsApp where she also admitted that she took the photo without consent but still refuses to remove the image. This is fraud and false advertising.
