Bad ABSA customer service

I have been banking with ABSA for 30years and I must say that ABSA bank does not live up to its own standards and customer support. After many emails and communications and phone calls via a private banker ABSA can not assist me in moving my payment dates. I received many feedback that the issue has been resolved and the next month the same notifications come through that I have missed my payment date and I get a penalty cost and bad credit record. The Ombudsman is even worse... I send them a mail in Oct 24 and only received answer in end Feb 25. I hope that through this platform I may received help. I choose this platform because I currently work in New Zealand and have been through many email communications with no solutions. Absa has not international email assists via an email contact and continuously refer me to call. Call land me up in a waiting line and a time difference of 11hours between New Zealand and South Africa. Messages on my phone came through a no number so please ABSA tell me who to call, because I am looking for ABSA no number line, department and contact person please. Phone +64
