Bad service at Standard bank & Standard trust. They cant keep promised and went people time and money

Standard bank has the worst service I've ever experienced. We lost our father january 2021 and he had a will with standard bank. Kaashifa was nominated as the execitor by the bank, the lady never contacted us. We kept emailing and calling her with no satisfaction until we lost our mom last in September 2021. Because im my late mom's executor i contacted Kaashifah about mom's share on my late father's estate. She told me everything is all done and the money is available to be transfered to mom's account. She even asked me to open and estate account for my mom's share. Then i went to standard bank protea glen to open and estate account in October 2021, i was heavily pregnant and had all documents. I was referred to Lenasia and i drove there same day. The lady Thandeka said she has emailed the documents for confirmation of letter of executor, then after it has been confirmed she will open the acc. Her and her manager advised that the protea glen branch should have done that for me. I visited the protea glen branch again and spoke to Tinyiko the manager, he spoke to Thandeka and even gave me his contact number to keep following up with him about the progress of opening the estate account which i did until march 2022. Whe. I went to the branch again i was told nothing was done. Thandeka did nothing and Tinyiko said him too had not received anything. I then decided to visit Cresta branch. I was given an email to communicate and make an appointment with a business banker. I emailed the lady with no response till today. I even went as far as contacting standard trust which deals with my late father's estate to assist, they advised me to send documents in june. And even said Ralda will be assisting, but Ralda doesn't answer emails. In july i decided to visit standard trust in hydepark and i met with the Langa who advices that nothing was done on my late father's estate and no money is available, no advert was placed. He promised to give me a call the next friday, that was never done. All this is happening because my late father made a will with stardard bank and its more than a year since he left us. Soon it will be a year since mom left us. And standard bank is just being an ass.
