Bad service in gender voilence at Pep store Germiston

What a terrible experience I had at Pep store àt Germiston - Goldenwalk mall where I was attached by a security guard, when I just entered the store and explained myself that I came to do Paxi and security guard(Mthethwa) insisted/ demanded that I go put my items by the counter, when I explained myself that I'm still taking a break as I'm heavily pregnant, then he said it's OK I can stand there but in rude manner, as I didn't wanna listen to him, I'm stubborn I can whatever I wanna do, when he continued saying all lot I then walked away from him as I couldn't stand his nagging, from my away going to next counter he then pulled me from behind and pushed me closed to store ranks that made me to loose balance, when I demanded to see a manager he continued to say I must live the store with immediate effect, when I asked him what wrong have I done, he couldn't explain, he then walked away without saying a word until Cynthia came to intervene to get more clarity on what was happening, but Mthethwa continued to walkway until he was called by next customer to come and apologize to of what he did to me, I'm still traumatized with what happened yesterday and left with a bruised on right arm, even scared to go near pep, I doubt that I will ever do my shopping in that store. Or even refer someone to that store.
