Registered for PAYE, but no PAYE Reference or Accounts Office Reference received

I applied for PAYE on 27th June, and received a confirmation mail. I never received an email with the outcome of this, or any post correspondence, but when I log in my company overview says I am now registered for PAYE. I urgently need to generate payslips, and pay them. How can I get the information I need, or generate the payslips without them?

Hi TomN_CCT,
These references would be posted to you, however if you not received them yet I suggest to contact us on 0300 200 3200 and we can reissue these. Please note we are not able to give these over the phone but we can send them again by post.
Thank you.
