HELP! I need to way to get hold of my full account number!

Description

Hi
I’m hoping someone out there can help me! I am trying to get hold of my full account number for my paypel credit account. I cant find it anywhere and on every letter I have received the only numbers that are showing of my account reference are the last 4 digits.
Is there a way I can do this? I have tried to phone PayPal but I just end up on hold for ages, and the ‘message us’ bit is not helping me because I have not had a reply since last week.
Thank you to anyone who can help me!
