unreliable foreign exchange services

I receive my salary via forex through Nedbank. I call the forex call center for my money monthly. This month, I completed a form at the bank that allows me to receive my salary without having to call . On 6 October 2015 the consultant at Nedbank Kenilworth assured me that I will not have to call this month as the funds would be deposited. I get paid on the 10th but the 10th was on a Saturday which means my funds would be available on Friday the October 9. No money was deposited into my account on 9 October. At 16:40, I received an email that my funds was received but I have to give a reason for it. I responded but received an automated email that the office closes at 16:30 even though I only received the email at 16:40. Forex is closed on a Saturday and Monday was a US holiday so I only received my money the Tuesday. My MFC car installment was debited the 12 October. MFC debited an extra R600 2 days later. They couldn't give me a reason for the extra money debited. On Friday 16 October they said it would be deposited into my account. Today is Monday, I called for my money. The claim was only put through this morning and I will only receive my money in 5-6 work days. It's bad!
