FNB Paypal assist - unable to address problem, continue to put me back to inquiries, spent 3 hrs on phone & nothing is resolved

I use PayPal to get international clients to pay me. I updated my primary email address on PayPal to my latest email. When trying to update my email on FNB online banking to match PayPal, my contact info does not change. They keep insisting it is changed or that it is the problem of PayPal. I have had several conference calls between FNB PayPal & PayPal. It is not PayPal. There is an error on the system, and FNB online banking support continue to pass the buck. I have had to repeat my story so many times, and re-do authentication also so many times. I explain everything, and they pass me on to someone who 'can assist' only to find out, they gave the wrong info to that person, saying I can't log on, which is not the issue. Then i need to start the cycle again.

Why have technical support when each technical support person I have spoken to seems unable to assist, and continues to claim the issue is addressed when it is not.
