Terrible service from Absa Idirect Insurance

I have an ABSA Idirect policy. I contacted them since I want to make some changes on the policy and wanted them to review it, since the value of my vehicles has depreciated. Lethiwe has taken my call and was extremely rude and first told me it doesn't depreciate, then she changed her mind after I told her it does. She then told me to keep quite and she will explain how it works. That was not the only thing I wanted to know but since she was so rude on the phone I have asked her to speak to her manager and obviously I'm still waiting! This is not acceptable, I would rather go to an insurance company that is interested in their clients and won't tell them to keep quite while you are still talking, I'm VERY disappointed in your unprofessional service and will find another company that can assist me without an attitude like this. The manager has my details and didn't even bother to contact me back.
