Card Division Emails deleted without being read

My wife app**** for a limit increase on her credit card. After a few initial queries from FNB, we were told that I needed to send a letter to FNB stating that I would stand as guarantee on her account. I drafted the letter and emailed it through to the address they provided me [Email Removed] The mail was deleted without being read. I sent it again and the same thing happened. I called FNB yesterday and they provided me with a new address [Email Removed] I sent the document through to that address and the same thing has happened. Can someone from FNB please contact me to provide me with a working email address so that I can finally send this through.<br> This is terribly frustrating !!!<br>
