FNB - Frankly Not Bothered!

I recently opened an Eazi account with FNB, they were the example of service I was contacted within a couple of hours to set everything up. My savings account is frozen and I need assistance but they are not willing to assist at all! I’ve tried calling, emailing, using their complaint facility but to no avail. I can’t get through to anyone when I call and when I email they suggest to call. It’s such a simple thing to clear up but they are not interested. I’m thinking of requesting a call back to open another account then maybe I’ll get some service.
