Worse customer service ever. False promises to a prestige account holder

I have been an account holder with Absa for 34 years, the last 4 years there service has deteriorated from bad to worse. I am with Absa private wealth for over 20 years and they promise certain benefits to prestige clients like myself. However in the past 4 years and more they have adopted an arrogant attitude, they are rude, arrogant and just don't care about customer needs & expectations. I've been asking for help now for the past 4 years with simplistic request and they have ignored or just disregarded my request. I have given them over R20 million in business the past 20 years, yet they have demonstrated no appreciation for that. They got agitated with me because for the past 4 years my problems still remain unresolved and I have not stopped requesting assistance. One of my issues in my opinion is very straight forward yet I'm still waiting for Absa to resolve.I paid of one of my vehicle's that they financed, yet after several years they can't provide me with my vehicles Natis document. They charging me monthly management fees of R540 and they committed to provide me a private banker to service my needs as a prestige client. I have had a maximum of about 2 F2F meetings with the banker in 2019. In 2020 and 2021 no F2F interaction nothing at all. In 2022 I had one F2F meeting with a banker, who noted my concerns however he never reverted with any solution. In January of 2023 , they appointed a new banker called Diwetse Direwe to oversee my portfolio. She came to see me F2F, noted once again my concerns and out of the 5 issues I raised, only 2 was resolved. In 2022, the banker who came to see me, a Steve McQueen told me directly that if I'm not happy with his and Absa service I can withdraw all my investments, savings etc and go to another bank. I eventually withdrew over R1.4 million in cash, and invested in another bank. He was supported by his line manager Barend Dunn. I logged several complains about their poor service and after 4 years, dozens of emails a senior Manger named David Monene called me. He canceled 2 meetings with me in the past all on the day we were suppose to meet and 2 weeks ago after years of unresolved issues, he now asked for a F2F meeting. When I questioned him why he canceled 2 previous meetings he couldn't justify his response or answer. Like his colleagues he blatantly and rudely informed me that I should take my business to another bank, and even if I took them to the Bank ombudsman they don't care because they a massive corporation and I'm nothing to them. After 34 years and over multi millions of business they got out of me, this is the treatment I'm now receiving. I want the public to know that they are the worse bank to deal with and the public should asks questions before they decide to join them as a client.
