PATHETIC SERVICE FROM FNB

I am extremely upset, annoyed and frustrated at the service I received from the Online Banking division. From struggling to make a payment on the banking app, I eventually logged onto Internet Banking. I picked the pay and clear option which the system decided to reject due to a duplication whereas their system didn't process the payment. Now an urgent payment due today will only reflect tomorrow as NOT a SINGLE person including the MANAGER "AVINASH" could assist instead I was indirectly called a **** as he had to get technical data to check it pay & clear was picked even though it reflected I had done it twice before which was rejected by the system. Asking for solutions, he kept reminding of the problem which the system rejecting the 2 first payments. Now after all my frustration I look *********** as an individual trying to pay an account. The WORST service I've ever received from any bank. It's sad and disappointing .
