Standard bank *******

Standard bank is the worst bank ever,they charging me arrears on an account that I've been paying forward,they say I owe legal fees from last year when my account was handed over 😡😡😡😡the messed up thing is that I was never informed and now they are threatening me on a weekly basis with their SMS saying I've agreed to pay, I've called and sent them messages on Facebook book but all they do is waste my airtime
