MISSING FUNDS FROM PAYPAL REFUND

I am shocked with FNB's client service and willingness to solve my problem. I am a customer of FNB since 2006, during July 2023 my refund via PayPal disappeared. Firstly I contacted PayPal, they assured my that the refund are released on their side and that I must contact my credit card issuer (FNB), with the authorization code provided by PayPal. Since end of July 2023 I am struggling to get help from FNB regarding this matter. I am kicked between departments like a soccer ball. PayPal refers me to FNB Credit Card, FNB Credit Card refers me to FNB's PayPal department, they refer me to FNB Forex department, they refer me back to PayPal International, no one can help me or are willing to try to get me to the correct person. I have all the proof and correspondence from PayPal, that they cannot assist me further, FNB must release my funds into my account. I also spend hours at my local branch, where the lady at customer Service also was kicked between customer service departments. This is draining all my energy and I am so frustrated after 2 months of searching for my money. I am considering to take all my banking to another banking institution. I have send emails, secure chat, phoned and visited my branch with NO answers to this matter. I am only moving in circles with this **** customer service!!!
