Not efficient

In 2021 a client had contacted FNB to pledge funds in my business account, during this time I had to sort this out in court and gave documents to FNB to release the funds, I had no feed back from the bank, no one at FNB could help me, I made calls visited the branch and still no help. In the past 2 weeks I've been calling and sending emails with no response not 1 personnel is making an attempt to call.
