Survey done by employee

On the 12th of February 2021 I went to KFC Wynberg main road and bought me food, the lady that works for Kfc( that sanatize your hands) comes up to me and asks me if she can punch in the code for the survey, I was like "yeah sure" because I was still busy eating and did not mind... But then she walked around with my phone and after a few minutes I was about to leave and I asked her what is she doing on my phone, and she said she is punching in the code, I was so confused and asked her a few questions, after I told her I'm going to leave I checked my browser only to see that she has been answering the survey on my behalf, rating them good services..... I was furious. I did not give her time to complete the survey, but I asked her was she doing the survey on my behalf and she **** to my face.
