WORST, TERRIBLE & DISGUSTING SERVICE

I phone FNB yesterday as I wanted to make a reversal and held the call for more than 30 minutes, as soon as I got through i was told that they have technical issues i should try again later. I tried again later, held the line for more than 30 minutes again when I got through i was told to verify my details. I told the consultant that I'm experiencing problems with their system as it always says i have entered incorrect ID digits. He insisted that I try and verify, it failed, he then transferred me, i stayed on the line for another 30 minutes. The consultant that answered was Fikile Nkosi, I explained to her about my experience with verification system, she transferred me again, stayed on the line for more than 30 minutes again till i ran out of airtime. I made that call again today, stayed on the line for 45 minutes only to be told that they can't assist me. I this how FNB treats their customers? Is this the best service you offer as FNB? I am so highly irate and disappointed by the terrible service I received from the bank I trusted. Worst of all I spent more than R400 on those stupid calls. FNB IS THE WORST BANK EVER.
