FNB Card Division... deaf as a post ?

So…I got an email and sms asking me to send FICA for my associate credit card in 14 days or face card suspension. Did so in the required time. Got ‘delivered’ and ‘read’ receipts but no answer at all. Then got another email telling me to send FICA in 5 days or card suspension would follow..Called Card Div and explained. Got reference number. Also re-sent the FICA with the progoinal recipts. Got new ‘delivered’ and ‘read’ receipts but still no answer at all. Fully expect now to get ‘final sentence’ email (death with costs). Why doesn’t Card Div respond ? Been to the local FNB Branch as well but they can't help. Guess it’s the usual Sabena.
