Query on fixed deposit account

On 27 July I opened a fixed deposit account with Discovery bank I then got an sms that it would be closed after 2 days if not funded I was not in a position to fund it for 2 days When I went back to my banking profile after 2 days, the account was still there, not deactivated, so I transferred my funds in I then tried to update the account to indicate where the interest must be paid and where the capital must be paid on maturity and got an error I then called their customer care today (03/08/2020) and spoke to someone who identified themselves as Mamsie I detailed out the issue as per above and she said she would call me back The call lasted for 10 mins 23 secs It has now been close to 3 hours since that promise to call back and there's no response This call cost me money I have already lost 3 days trying to understand how things work with this bank, on their app and failing How long must I wait further I no longer want their business, they seem unbothered by the deficiencies of their offering and the lack of transparency & power extended to their account holders on the banking app, making it necessary for clients to spend money making calls to speak to people who make false promises about getting back to you on your query I just want my money released, they have breached whatever agreement was in place as I do not have the account active, nor is there any interest as promised. I deposited the money on 31 July, so that day's interest should have been paid out.
