impossible to get any email response re expired card

I have been trying for weeks to get an email response from "care@fnb" with no result. I've sent three separate emails and only had autoresponses (and possibly missed called with nobody bothering to leave a message) CCD couriers are completely unresponsive and their only available email gives an error message. I am NOT available by phone.

please send me an email that will actually get a response regarding my expired card? It was urgent 2 werks ago, not it's just *********** and rude
