Awful account administration locking out subscription

Every month, Sage Payroll locks us out, creating barriers to preparing payslips, on the basis that they are not receiving subscription payment. Yet, a debit order has been running smoothly since day 1 of the subscription. Numerous attempts to rectify their Finance teams continuous errors have proven fruitless, as the issue keeps recurring, month after month. Worse yet, this issue has previously been reported on Hellopeter, still with no permanent resolution.
