Absa bank is letting his clients down

I have been struggling to get business papers from Absa, From October 2020 nothing big, papers just have to be signed, they told me to contact my business representative Thembi Makaphula, I phoned, I emailed, no response, when I phoned asking for her manager's number I was met with attitude and when I told the person I was speaking to that I am not happy, she actually laughed at me, This is unacceptable
