FNB needs to catch a wake up

With identity theft a real concern, FNB needs to seriously look at their way of dealing with customers. <br> <br> I requested for my cheque account to be closed earlier this week. <br> <br> I just got a call from an Unknown number. It was FNB. To verify that it is me they want me to give them personal detail. How can I be sure it is them?? <br> <br> Stop phoning from Unknown numbers or find another way to interact with me. <br> <br> But, not my problem anymore. Luckily I am no longer using FNB as my primary bank.
