My account is blocked because African bank teller couldn't update my documents in time

I'm a ZEP permit holder and also app**** for a general work visa. I went to the African bank branch to update my documents as their request 3 weeks ago. I was told that everything was send to their headquarters for verification and update, but to my surprise that my account was blocked on the 29th of November. I went to the same branch on the 30th and they told me that they were waiting for the headquarters to respond. I called their call center but I'm being to wait but no ETA,then I write a review on this platform. Their support team called and said they are going to follow up with the branch on Monday but nothing was done. I then called the branch and they started giving me excuses that the bank teller is sick and she is the only one who can access even though there's Incident number (***1). Tuesday I got hold of their support team via email and confirmed that they are going to resolve this issue as soon as possible and I might have the answer by afternoon and that was it.Yesterday I went there again then found out that my documents I submitted 3 weeks ago was not even added on the system, it was done yesterday afternoon. I can only log on my account using that email link but my card still doesn't work. Today I was at the branch but they don't know when my account will be unblocked. Please help me, l have family to support and pay my bills. Electricity and everything that a person needs to survive are running out
