FNB Virtual Card

I am having problems making purchases using the virtual card since last week, previously it worked fine. I called the agent and spoke to the following people Segodi, Nomande and Lebogang., none of them could help ,to date the VC is still not working on my phone, i spent over 2 hours on the chatline with no joy. and no one even followed up to check up on me if the VC was working , that says so much for your service . please could someone help me with this as it affects my reward program. Also why don't FNB train their agents so they can handle these problems, its very frustrating for the customer to wait hours for problems to get sorted out, its a crying shame to FNB managers who are not handling the call center agents.
