Bad customer service

Onthe 14th of June 2018 around past Five, I went to Pep Store (Clothing) at Westgate Mall with my two colleagues to do eye shopping, then we left the store and apparently one of the floor staff followed me and my colleagues to the taxi rank and she told me that I must go back to the store and then when we get to the store that staff member didn't have her name badge on, she told me to getting to the fitting room and I asked her why, she said she want to check in my back that I didn't anything from the store, I went in to the fitting room she checked and she didn't find anything and she didn't even apologize for humiliating me in front of the customers and my colleagues and am still angry even today because I called Pep Store head office on th 15th of June 2018 and told them what happened , they said the will contact the regional manager, then I got a call from the lady and her name is Thuli and she apologize to me on the 20th June 2018, few days later I got another call from Simphiwe also to apologize on the 23rd June 2018. Even today the lady (Khosi) who humiliated and accused me of *****ing didn't apologize. And I call the head office again on 6 of July 2018 telling them that lady (Khosi) and didn't apologize and I demand compensation because that lady (Khosi) disrespected, undermine, and humiliated me. The worst part is that I was in that same mall with that lady and I don't feel free and safe anymore!!! Please help me
