Terrible service.

We have a LARGE (Approximately R290,000,000.00) business deal that we are trying to get sorted. Obviously this is worthwhile business for FNB as well. Our client needs to submit an LC to our account. We have been dealing with someone to have them assist us in the process. We have been trying since last week Thursday to get this done and nobody seems to be able to point us in the right direction. We are being given incorrect information and are no closer in the space of a week, to concluding this than when we started. I find this service appalling to say the least. We look like complete amateurs with our client and are now at the point of moving banks to get this finalised. "How can we help you?"... Apparently you can't.
