SAGE - "proudly South African"? NOT

After paying an annual subscription for two companies in Dec '22, we then found out that Sage could not calculate interest on overdue customer accounts, so we cancelled in early 2023 and requested a pro-rata refund.

Numerous emails back and forward have followed, including sending proof of bank account details on 8/11/2023. I was promised that a refund would be processed after 14 days on 30/11/2023, despite the banking details being with Sage 3 weeks before this, and now, on 6/12/2023, I am being told that a credit has been passed, and the refund should be processed in 14 days - AGAIN!

I have tried escalating to "supposed" managers who cannot be reached telephonically as their numbers just ring and one cannot even leave a voice mail message.

We want to be proud of our South African competition to XERO, but how can we be if this is the standard of customer service? How can I even recommend Sage as a supposed "Partner", if this is how clients are managed?
