Bank withholding my money due to their incompetence

I deposited a sizeable amount of money into a 32-day investment account and on the same day, I gave notice that on the expiration of the 32 days, my investment plus accumulated interest was to be paid into my FNB account. When the notice period expired, I went into African Bank and spoke with the same individual who I Had opened the account on my behalf. He then checked my account and told me that no notice period had been given.

So, after expressing my annoyance due to his negligence, I gave notice once again fir the account to be closed in 32 days. This was also confirmed via a telephone call from the bank, to one of its online consultants. However, after 25 days I decided to go into the bank once again, because none of my instructions to have the account closed were provided on my account when I opened the bank's app to further verify that my explicit instructions were been followed, which they had not been. So, once again I had to deal with the same clerk in the bank, and yet another online consultant from African Bank. And of course, they both verbally confirmed that my money would be paid out and deposited into my FNB account, which has not happened. And when opening the bank app and checking my account, it shows that no notice period has been given.

African Bank are ******. If I had invested at any other bank I would have earned higher interest, the account would have be3n closed 64 days ago, and I would have received my money. NEVER will I trust African Bank nor will I ever recommend them.
