FNB no good

I have a savings account with them. I lost my job due to a injury on duty and have not used my account as there is no money to deposit into the account. Friends and family tried te help me by sending a ewallet but FNB has blocked my number so that I cannot receive anything. Is this even legal? I will most definitely not make use of FNB ever again and would not recommend them to anyone, if they should encounter any financial difficulties make sure to close your account with them bacause they want their money no matter what. You can starve of hunger but you will have to pay them your monthly fee.
