African Bank IT Department The Worst!

Opened a fixed deposit with African Bank on 14 Feb 2019. I invested a huge amount of money there for a period of 60 months. I've been unable to register and log in online since day 1 I opened the account. They keep on telling me that my mobile number is not recognized. I had to go in twice now to the nearest African Bank. I've phoned the helpline and they refuse to assist me over the phone, telling me I need to verify myself at the bank. Its now 16 March 2019 and I still can't register or log in online. When I went in to the bank to verify myself again, the IT department said they will give me feedback on 22 Feb and my complaint will be resolved. I've been given 2 reference numbers and been told many times that the IT department is still working on my complaint. Is any one in that IT department even qualified ? This is pathetic! My mom literally had the exact same issue/complaint and it took them 4 months to resolve it. This is the worst service and experience I've had at a bank.
