Hit a brickwall with adding services to my acount

I am a foregin national living and working in South Africa. I conduct my business online and receive my payments mostly via PayPal. Late last month I went to the Mobeni Branch to open an account as FNB is the only bank in South Africa that currently allows funds to be transferred from your PayPal to your local FNB account. I then opened a Paypal account using my new FNB details. That happened without glitch. Then the horror started when I wanted to link my paypal with my FNB account. I got a message that said \You are Registered on the FNB system with a passport number. Passport numbers cannot be used for PayPal transactions. Please update your profile at the branch with the number of your Temporary Residence Permit". No problem"
