Get your priorities straight

I was offered a nedbank credit card on my money app recently, I accepted it online, but within the same week I phoned the agents and asked them to cancel it as I made an error and dont want the account..Never used the account at all and told agents to please not record this on credit bureau it was error and while im in process of purchasing house I dont want this to bring down my credit score. The account was still sent to bureau as closed and brought my score down..In that same week I also settled my nedbank personal loan which is not yet updated as paid up on bureau. THey could quickly send credit.card that I never used to bureau but cant quickly send personal loan paid up status to bureau. How does that work. I WANT THIS UPDATED URGENTLY.. Their complaints dep said the closed acc status will show on bureau forever...also experian said they just waiting for nedbank to send instruction and they can remove it immediately..someone is lying here
