How to contact ACCA

I’ve recently become a member of ACCA, and I’m unable to contact ACCA in the new portal for members. when I emailed memebers@acca they said the email is no longer in use and pls use the portal but I can’t figure out how to contact via portal. when I go to contact us button the portal it only shows FAQs no way to contact them. I’m having trouble downloading the invoice for membership admission fee which I need to claim the reimbursement from my employer, and no way to contact them. this is just so frustrating. Please help me.
