Default notification was address to unknown address,, multiple default and dispute being in favor of the credit provider that's using incorrect information only name

I am not sure what credit bureau look at to register a default under your name , I have a default by debtcor registered without being informed I disputed many times they're said credit provider gave them notification evidence I requested that's evidence to see, first of all the address is not mine I have never been to Pretoria, never stayed in Pretoria never ever sign or accept any notification or letter of demand I don't know to who this notification was sent too why this provide lier's and believed by TransUnion I am struggling to get employment because of default issued without my knowledge, I have stayed in Kwazulu Natal for over 15yrs moved to Western Cape in 2022 I don't know this Pretoria address even if the landlord or property owner can be asked about me they don't know me Why I am being punished for something I don't know what was never ever sent to me.an TransUnion agent advise me to contact credit ombudsman and they're rejected me telling me my case it not within they're jurisdiction so who's going to assist me removing this default because no one I mean no one ever advise me on my number, email why the unknown post was used? Why it why listed twice 7th and 13th November 2023 same amount different reference or account numbers Why the provider is the one being allowed ruining my profile with unverified information that's notification was not sent to me I don't know that's Pretoria address who updated it and Why , so where must I go now for this to be resolved? I can't just allow this this people are lieying I was in Western Cape in 2023 I have all the proof of that
