Unprofessional bank for private clients

***** department at FNB froze my account and I had to call them numerous times to get an explanation of why my account is frozen. I received payment on the 16th from a person and I transferred it to his capitec account account , On the 20th I received my salary and my account was blocked, I submitted the affidavit explaining the issue of the funds received which I sent back, and they responded that it’s not enough. I have been sending emails from that day with no response I am very frustrated because I don’t have any money, I work very hard to receive my salary and when it comes through they block it. My kids don’t even go to school anymore because I don’t have any transport fee.
