Disappointed by rude consultant

I'm REALLY disappointed. If this is what the service is like at FNB from the get go then its really not worth it. DSV contacted me to deliver my card and my sons card. I gave them my address and details. I only received delivery of one card. I then contacted FNB and then DSV and then FNB again. Whilst I was speaking to the consultant at FNB I very calmly told him that I am not happy with the mix up and I would like to go through to someone who can handle my complaint to DSV as DSV is a service provider for FNB. The gentleman simply hung up...how rude. FNB does not consider the needs of its clients and does a sloppy job when it seems like they actually are attempting.
