Unauthorized hard enquiry on my credit profile

I'm still entirely dissatisfied regarding the feedback I got from a Social Media personnel with Cell C, Busisiwe Khumalo. Let me start by saying Khumalo is pretty much clueless about the Credit Department's processes and was not the relevant person to engage with me on this complaint I lodged on this platform with ref ***, with regards to Cell C, conducting a hard enquiry on my credit profile. Her job is mainly to attend to social media complains and to protect Cell C's reputation. I still need to speak to someone in the upgrades and credit departments who will tell me why they ran a credit enquiry on my credit report without first seeking my permission or contacting me, as I'm 100% sure that I have blocked all calls coming from Cell C and had no missed calls non whatsoever on the 8th of September 2023. To say Cell C cannot reverse the enquiry the made is nonsensical. She went as far as asking me what impact will the hard enquiry do to my credit profile to further expose her lack of knowledge and information as she could not tell me the difference between a soft and a hard enquiry on someone's credit profile. I'm also waiting for her manager Gift Masina who should have could me already but decided to send me a junior staff member who cannot articulate themselves in English. Cell C Credit department, I urgently need you to remove all the unauthorized hard enquiries made on my credit profile, as this is going to stay for at least a year on my profile. Failing which I will then contact the Credit ombudsman.
