Disappointed client

I write this review in distress with the current pandemic we are facing. I had visited my fnb branch crompton st pinetown to make payment as my account was in arrears and I am expecting payment from a client on work done prior to the lockdown, upon speaking to the consultant I was told that my account was closed indefinitely and that I had to pay R743 for it to be re opened I told the consultant that I have R400 on hand, can't the bank debit the rest when funds are available in my account as I was promised payment immediately. I even showed the consultant invoice sent to my client but was declined due to not having enough funds ,its though being a small business owner , especially during this Covid-19 lockdown period .
