What a bogus store they treat people like *******

So disgusted by the Pep at park station went to the store only went to the front till the next thing when I went out I opened the bag for the security guard I didn't even hesitate there was sweets in my bag but I told him I didn't buy them there he said I must produce a slip but I didn't have it so they said they are taking it away. So I insisted that if he says I stole them why can't he review the cameras the guy was so rude he said he is not gonna do basically he is saying I am *****er so to prove it I tell him go and view the camera but he refused so he practically stole from me without proving I stole so I must prove so I want them to check the barcode and see if it's the same am really ****ed cause I was treated like a ***** and they can't prove it so am going to escalate this even further, am totally disgusted with such rude behavior.
