Cheque Account not linked to profile

I've opened a gold cheque account with FNB almost 2 years ago, whcih I upgraded to a Premier Cheque account - All online or ueisngthe App, easypeasy. Got my cards via courier, using my account daily....

I then opened a Businees Gold Cheque Account - also online - alsogot my card.

Went to the Branch over December, sat there the whole day..... They can't pick up my personal cgeque account on my profile. I phoned FNB, none of the "bankers" are able to assist me, because they cannot pick up my account.

What the hell do I do now??? If they don't know, how am I supposed to know?
