Call centre service and systems failure

I have a long standing existing policy with this company. It covers multiple properties. More than a month ago i requested a new property to be added and existing property details to be amended. The new property has successfully been added.

The amendments to existing properties have not. Since then I have record of me following up and re-requesting these amendments at least 9 times, either by email or phone. Every time a different person handles the request, so I have to effectively start the process from the beginning. There seems to be no thread on their system of my requests. This is serious call centre service and systems failure.

As I write, I have been waiting to speak to a call centre supervisor in a hope to get this done. I have been waiting on the line for more than 17 minutes and giving up now.

ABSA is close to losing my business.
