***** case not being settled until now, no feedback

My credit card has had a ***** case ever since 2 May 2024, I have been making follow up on the status of progress till today , when I call the ***** unit they kept on saying the matter was escalated to the management and they would revert back to me, the worse part is on my credit balance that amount which was ****med is still included, their customer service is so bad i don't want anything to do with FNB,I want to settle my credit and look for another bank
