Forex Outward Swift payment

Not Sure if FNB understand time costs money. I did a Foreign Outward payment of $55 000 and I received a email that also shows the Value date which was the 30th. I have forwarded this to my Agent oversees and advised that I would send them the Pop once I received this. So yesterday came and gone. Today the 31st I received email and they needed changes to be made to the invoice and asked additional questions. I emailed this back immediately and advised why only ask the question a day after value date. I understand the reason for the questions. After each response it takes hours for feedback. The last consultant after I send the amended Invoice now tells me there is no changes. But this was added clearly to the bottom of the invoice. So she never looked properly. Guess what now I tried to get hold of them, they closed earlier. Who is going to pay for these losses, I am trying to run a business here. Now my customer is asking how far we are????????????????????????????????
