Accused of theft

This afternoon just after 16:00, I was a PEP stores Letshoho shopping centre in katlehong,I entered the store with my hand bag that had all my personal belonging,inside the bag I had wet wipes that are PEP brand,upon leaving the store my bag was searched and the wet wipes where found in my bag,the lady by the name of Dude quickly accused me of *****ing,I explained to her that I had bought the wet wipes the previous day at PEP Alberton,I further open my bank app to show her my transaction that I was at PEP stores,she called her Manager by the name of Paulina who embarrassed me in front of other customers and took my wet wipes away,if I indeed ***** the wet wipes why did they get me arrested for theft and why didnt they take my details for record should I want to go get my wet wipes because I do have the proof of purchase with me here at home,Im a regular customer at PEP stores and this is not the first time Dudu has mistreated me,she always has a bad attitude towards customers as if we are there to beg,Im not happy with the way I was treated and I deserve an apology.
