Pathetic service

I tried to invest R500000.00 in a fixed deposit account, they gave me incorrect information that I could convert my one saving account to a fixed deposit account. When I tried to deposit the funds into this fixed deposit account via internet banking I could not. I called the bank they could not help, that happened on 22 March 2023. I have sent 4 emails to the bank with no response. I eventually got a reaction after I reported the case to the Bank Ombudsman. However today is the 2 May 2023 and the problem is still not resolved.
