Poor poorest customer service at African bank

Hi Poor customer service at African bank. I open an investment plan on 24 march 2022. I did not receive the welcome letter from African bank, I decided to go to the branch on the 14 April 2022. They refuse to assist me further, there told me my account is not opened is still on pending status it says being reviewed. After that I receive the email on the email there's where I can click if I want to deposit money. I clicked and then diposited R50 and then the next week I called them and I speak to consultant and she said she is transferring my call to the relevant department, they did not pick up my call, I hold until 2 hour nobody responded, tomorrow I phoned again and they did not respond again. This morning I received the sms saying they have closed my account due to non funding, It seems as if they did not receive my deposit of R50 even now.i was hoping to deposit more after they acknowledge my deposit.
