Identity ***** case not cleared on my profile

Hi , I had a contract with vodacom for many years the a last year there was "Identity theft" happening with my details wich changed my contract without my knwoledge and opened other contracts with other providers .

I managed to alert ***** departments with all the providers involved (Including Vodacom). they all investigated and confirmed it was a ***** case(letter sent to me). all other providers updated my profile and cleared my name with Experian/Transunion except Vodacom. Tried to reach out but nothing happened . I can't apply for anything now as the case is still reflecting on my profile... How hard is it to clear my name even after you investigated the matter
