FFG is Rude

I have an account with them, when I went to pay for my monthly instalment their cashier paid it in to the wrong account and it’s been 3months now since they said they will fix it, instead they sending me back and forth to no help or refunding me, I wish they could use the same energy they have when they call us when we miss payment to resolve this because my account is always up to date.. I really don’t understand why am I getting sidelined because the very same weekend there was a lady that had the same issue and hers has been resolved but mine not.. so I am not sure if they are scared of whites or they treating us differently.. I am really ****ed and disappointed at them cause they are rude especially their head office because at their store they willing to help but they can’t do anything without their head office approval..
