Cell C Customer Service not meeting committed timelines

I've been trying to un-blacklist a hand-set following the chaos of a house ******* where a handset was blacklisted, but found after the fact. I submitted the required information on 20-Jan-25 (Ref ***). Upon follow-up on 24-Jan-25, I was told to re-submit the documentation, which I did (Ref ***). When I followed-up gain on 27-Jan-25, I was told to send the documentation again, which I did (Ref ***). After submitting the required documentation three times, and having to make at least three follow-up calls, I am no closer to getting the handset un-blacklisted. Cell C auto response advise that a Consultant will contact the Client within 24 - 48 hours, however after five working days I am still waiting for a Consultant to contact me, or resolve the issue.
