Phone damaged at VODACOM STORE!!!

Purchased a brand new phone (Samsung Galaxy S10) with Vodacom with my contract renewal. I (and two other persons - my parents) went in the the lower floor Vodacom store at OR Tambo International Airport in Johannesburg to purchase a screen guard for my phone. The individual by the name of "Lucine" at the front counter told me they had to take my phone to the back to apply the screen guard. I then asked her if I should remove the original screen cover that came with the phone which she agreed to, following which, she took my phone to the back as I waited. The individual "Lucine" then returned with my phone in her hands, SEVERAL minutes later and put the phone on the counter, appearing only now be applying the protector, she then stopped and said... "I see you already scratched your phone". I then looked at her in absolute shock and awe because this was not the truth at all, I had brought my brand new phone to this store which was just as brand new with no scratches or damage as when I had first taken the phone out of its original Samsung packaging. I looked at the scratch as she showed it to me and knew immediately that this could never have been done by me! I told her that my phone was brought here without any scratches and clearly the phone was damaged while she was handling it. This woman insisted on an argument in a very disrespectful manner that she hadn't scratched my phone and was quick to make up a story and say that she will get her boss to give me CCTV footage because apparently in her words: "the cameras in the store can show from "EVERY" angle that she didn't scratch my phone". I knew that this woman was not going to be honest about what she had done and would carry on fighting and arguing with us and denying responsibility that Vodacom should be taking for her what she had done! My parents and I took her details down as we were in a hurry because this individual not only wasted my time, damaged my belongings and sent me off as an upset and heartbroken customer of Vodacom, but she was also about to force me into missing my flight overseas due to her pathetic attitude in arguing and profusely denying responsibility! I had to leave the store and rush to catch my flight. I had to be overseas with a phone that did not have a screen protector on it and I have had to live with a scratched brand new phone which is no fault of my own because of your careless employee! Because of my being away overseas for a while, my father had complained the to branch manager of this Vodacom store at OR Tambo Airport and he received the video footage back from this individual with a long essay this individual sent back full of excuses and shifting the blame back to me as a customer. If it mind boggling for me to think that this so called representative of Vodacom thinks he can speak to a customer like this after everything that has happened! Up to now after being back in SA, because of Vodacom my phone still doesn't have a screen guard to protect it until this matter is resolved! He is basically covering up and not bothered to understand and do something about correcting this situation. I am supposed to be enjoying a brand new phone which I am paying Vodacom for an exorbitant amount of money each month and this is the thanks I get bac**** I have been a customer of this pathetic company who I've experienced countless issues with, unresolved issues that just go off the radar conveniently by Vodacom's PATHETIC service standard and now I am fed a bunch of excuses for my phone being damaged while one of your staff at your Vodacom store was handling my phone!! IS THIS FAIR on me as a customer??? I trust that this matter will reach the highest authorities at this company and be resolved with immediate effect! Until then, my phone remains without screen protection and I am having to live with the strain of this issue you have caused!!!
