Pledge placed on my Premier Cheque Account

A pledge was placed my premier account - i really don't know what this means. After calling the premier banking telephone number I got hold of Sibusiso, he introduced himself and the call ends. He does not call me back. I logged onto secure chat on the app, Asanda assisted stating my balance is what it is. I am telling her from the screenshot I sent R********* amount cannot just disappear from my account. She is inexperienced and could not help. I asked her to escalate my query to her team leader or manager or call me. She says she cannot. I called the premier banking line once again and got through to Cebisa. I asked him were had the money from my bank account disappeared to if I did not transact. He says R******xx amount is under Pledge. Why would my monthly salary go under pledge together with my SARS refund. I can understand if just the SARS refund amount was queried but not my monthly salary. Cebisa told me he will transfer to the Accounts processes and I must find out how long it will take for the pledge to be removed. Once transferred I had to leave a voice message. To date nobody has called back. FNB your service is PATHETIC. It's atrocious how clients are treated and how easily a bank can *******ly withhold funds from a client’s account without my permission. This is my monthly salary, I have debit orders coming off on the 1st, who is liable for the returns. Definitely not me FNB…………… Please get someone competent enough to assist… REF:***
