Experian SA: never gets back to you, never wants to resolve issues

I had an issue with Experian not getting back to me, about sorting out missed MTN cellphone payments on my credit report from 2021, as I'd repeatedly told them that it was due to identify theft. I'd provided the required docs numerous times since then, including multiple affidavits.

Earlier this year, after one of their consultants requested documents yet again in Feb, I supp**** them - but they didn't get back to him. After numerous follow-ups, over months, I complained on HelloPeter and someone contacted me. I again supp**** the documents and my story. It's now been over 2 months yet again, and they haven't gotten back to me. A month ago, I logged a complaint with them about not getting back to me. I just tried calling them now - I have been on hold on a call just now, holding for 20 minutes, to get answers but to no avail.

Honestly, they actually just don't care. When they do eventually get back to me, they'll repeat that they want an up-to-date affidavit, yet they are the ones who don't get back in time to a person before THEIR SELF-PROCLAIMED validity period for an affidavit elapses.
