FNB unhelpful Forex department

I am having issues with FNB Forex department. I made a payment and I emailed the supporting documents on the very same day I made the payment only for them to email me asking for the very same documents I had sent. I resent them and I'm still being given the message that we will respond to you asap . This is not the first time that this has happened and they are totally unhlepful and unprofessional as this affects a cleint's
