Shouting Sales Consultant

I was at Nedbank Sunward Park last Friday 21 August to open my new banking account, I was helped by Sibongile Sejake, a sales consultant, who provided me with such average service, A brand new client I expected more, I received a call today to say my overdraft was approved. I said thanks and my credit card to which she said was declined, I said how is that possible I have a brilliant credit rating what can we do now she shouted well it was declined for the second time I appealed it there is nothing more I can do, I said but I want a credit card, I have always had one, again very rude and shouting at me I said I want to speak to the branch manger, who too was not of top quality. Good grief, Sales consultants these people need training is Nedbank just employing people with no sales experience at all, It would appear so. Brand new client and I am totally put off and disgusted, think I will be moving along to FNB.
