Disappointed. No service.

I have been a client of ABSA for YEARS! I want to change my account. I have contacted ABSA via email and on their portal on the ABSA website. I received an email a few days later requesting information and I rep****. Since then I have been trying to get hold of ABSA with no luck. I want to use their product. Should I go to a different bank?! I am so disappointed. This is absolutely the worst service I have "not" received at ABSA.
