No service from Sage payroll renewals

Good day, we've paid our annual subscription for payroll on a pro forma invoice. The details on the invoice is outdated and after numerous emails sent, I receive no reply. I need to get this corrected. Apart from this I have been emailing *** to assist with updating our product. But it seems this email is not working. Is there anyone at Pastel/sage payroll who can assist us. This service is sub par, and not acceptable.
