Bad service from African Bank

I opened an investment account January 2020. After few deposits, 2 of those they said they didn't receive but the account was linked. Went to the branch few times and called few times but a year later they are still investigating not even providing feedback. I am so frustrated i had to close that investment account but i need my money back and they are dragging their feet. Be careful with this Bank, you give people a chance and this is the treatment you get. They promised better returns but if you will lose your money its not worth it.
