My lump sum deposit disappeared to thin air at AFRICAN BANK

I deposited a lump sum in my African Bank Tax free saving account on the 05 Jan 2022. Until today the lump sum is not reflecting in my account. I visited the branch and also called the savings and investment department, the consultants cannot tell me where my money is. Can African Bank give me my money back instead of sending me from pillar to post with no answers. Your customer service is the worst I have experienced, I regret trusting you as a financial service provider. It has been unpleasant doing business with you AFRICAN BANK!!!!!
