Absa Enterprise Banking service sucks

I have been unable to get hold of my enterprise banker at my branch. He does not respond to emails and the phone number remains unanswered. I logged this issue with an email to my business banker help center. They responded with a case number and informed me that I will get a response from a consultant. That was two weeks ago and despite two follow up emails I got no response. This service is unacceptable. Sadly it's not the first time I am not getting any response from our enterprise banker.
