NOT GIVING FEEDBACK

every month I do have access to Temp loan and when I got paid the bank deduct the money immediately, but this month when I am trying to access the loan it doesn't allow me since the 25/03/16. So yesterday 30/03/16 I send them mail and somebody just read the mail but no feed, today again I send another mail and somebody again just open the mail and read, not responding, I used all the money as I know that every month I do have temp loan with my bank, I have been banking with FNB from 01/05/2005 to date, my salary was transferred to this bank since 2005 but now they are giving me problems. If I can't have access to temp loan within 24hs I am taking my business to Capitec because I already have one account with them, I am going to ransfer all my debit orders to Capitec if I am not assisted.
