BAD SERVICE -Sage South Africa

I suddenly received an invoice for August 2018 in September 2023, five years after the said period. Everybody that uses sage partner, knows that you have one month's grace period to pay the bill, then it goes into "view only" mode. Back in 2018, you had to call partner to get an registration code, which an operator in registrations read out to you and you had to physically type in. I have been struggling since September 2023 to get this sorted out. Instead, I receive e-mails stating that I have been handed over for not paying the account. There was apparently a journal made to remove the payment received, to somewhere. NOBODY IS RESPONDING! I have sent e-mails, made calls, every month for the past year, and still nothing! Today, I received my overdue statement for September 2024, once again! a Friend that uses Sage has experienced the same issue. If Sage cannot help their customers with account queries, why are we using or trusting Sage Partner and Payroll with our business?
