PLEASE HELP. I AM VERY FRUSTRATED WITH POOR SERVI

I SUBMITTED AN APPLICATION WITH FNB ON 11 MARCH 2015. I HAVE MADE NUMEROUS CALLS, SENT E-MAILS BUT WITH NO RESPONSE. ON TUESDAY I WAS PROMISED AN ANSWER THE SAME DAY AND AM STILL WAITING - NOT EVEN A REPLY ON MY FOLLOWUP E-MAILS. I HAVE JUST SPENT MORE THAN 21 MINUTES ON THE PHONE WITH A CONSULTANT ONLY TO BE TOLD THAT IT WILL ONCE AGAIN TAKE 24 - 48 HOURS. IS THIS THE STANDARD OF FNB. SURELY SOMETHING MUST BE DONE !!!!!! I HAVE BEEN TOLD THAT I NEED TO RE-APPLY AS MY APPLICATION GOT LOST AND HAD TO BE SENT THROUGH 3 TIMES. NOW I AM TOLD THAT THERE IS A BACKLOG AT CREDIT DEPARTMENT AS WELL AS THAT MY APPLICATION HAD BEEN \NTU"(ABSOLUTE NONSENSE) """
