Attestation of Compliance or SAQ D for Service Providers from WorldPay

Hi all!

Our PCI Compliance team at the University has requested an Attestation of Compliance or SAQ D for Service Providers from WorldPay.  I have tried WorldPay's general email, but it bounced back.  Does anyone have a suggestion on who to contact at WorldPay to get this information?  We have had difficulty in the past trying to get information about our account in general.  I appreciate anyone's help!

Best,
