RUDE SECURITY HARASSING CUSTOMER

I always go to Pep Home store in Somerset West main road and i love that shop, however since March 2023, I"ve been harassed by the security at the door.I know that the security can check your bags if you don't want to hand it in at the parcel counter, but with this security i told him numerous times that i am going in the store with my backpack which contains my work laptop. I also indicate to him he can search my bag when i leave the store. When i leave the store, he decides to open and search my backpack, right in the doorway, where outside onlookers can see that i have a laptop, wallet and other valuables in my backpack. I've asked him as well not to search my bag like that, for my own security reasons, as there are always people loitering outside the store.The weekend before Easter Friday, had the same argument with him, however 2 men in front of me had backpacks on and they were not searched when they left , yet i was. The same thing happened in May and i told the Manager who was from Gordon's Bay about his attitude. She searched my bag and looked through it in one of the aisle. Today the very same thing happened, and i just had a see-through plastic bag with pencils in it. He made a scene and told the teller in Xhosa, whenever i come in the store, i am there to cause problems.I told him that i heard and understand what he said. I explained the situation to the current manager, Zee but i don't think talking to him will help as he keeps harassing me when i go to that store.All the other Pep stores in Somerset West, has the nicest security and they always greet and never have i received the same treatment from them as with the one from Pep home. For a usual customer to be harassed and abused like this to the point that his actions may lead to me one day getting attacked or ****** is unexceptionable!Now i get anxiety and ptsd because of this and enjoying my shopping experience at one of my favorite stores.
