Billing No Longer Applicable

<p>The company elected to no longer use Pastel Payroll, hence did not renew the license this year. After unsubscribing to the SAGE email list, I was sent a statement with 4 promptly created invoices. I have sent various emails to the addresses provided explaining the situation and requesting credit notes. I have receipts that the correspondence is being read, but only get another billing invoice. I have called to attempt to resolve this telephonically and have been transferred to the training department, the technical support team and was told by the finance department that it's not for them to deal with, I need to speak to registrations. The telephone numbers I was given me either do not exist or remain unanswered. So, I have wasted an hour depleting my airtime with no results. Any suggestions? </p>
