No results after explaining

So it's been a month now going up and down, case being dragging, every one I spoke with says they will escalate the matter it will take only 5 days to be resolved, guess what since the 17th of September,till today only to be told I need to submit a form that I can't obtain after explaining my issue to so many people, to top it all,they not even providing ref no for all the calls,the 2 people I spoke with said I should get a DSH screenshot from NRC that will be enough to resolve my case,ive send it,which was 17 September, they said I should came back after 5 days all will be sorted, only to be told that they will escalate the matter I should wait 7 days,we'll after 7 days the person who picked up the call "escalation department " says they didn't receive the document ive send it should send again and wait 5 more days,we'll its still not resolve, now they are asking a form 19 that I can't obtain an i explained to them why,they understood, hence they requested a DSH screenshot.

So capitec bank what should I do now since we'll you asked for a document,escalated my case 2 times already, only to go back to step 0 were it all started and no result come out of this escalating
