Failed AutoSSL preventing new SSL Certificate Installation

Our Cpanel SSL expired yesterday. I purchased a new DV SSL this morning, but it is stuck saying "Payment Completed. Awaiting Validation "", the logs from today says: AutoSSL queue already contains a certificate request for "lntsoftware""s website "coolcare4.co.uk". The request"s start time is Jan 30, 2022, 1:01:02 AM UTC.
This is for our main company website so really need this back live asap but CPanel haven't responded to my email and there seems to be no control to cancel the pending SSL order or retry the new one. More logs: Logs from 30/01/2022 1:01:11 AM The system will attempt to renew the SSL certificate for the website (coolcare4.co.uk: coolcare4.co.uk www.coolcare4.co.uk mail.coolcare4.co.uk lntsoftware.com www.lntsoftware.com mail.lntsoftware.com webmail.coolcare4.co.uk cpanel.coolcare4.co.uk webdisk.coolcare4.co.uk cpcontacts.coolcare4.co.uk cpcalendars.coolcare4.co.uk). 1:01:26 AM The cPanel Store received "coolcare4.co.uk""s certificate order.
