Poor client service and delay tactics

The only bank that will always be on time with debit order and sometimes even before the agreed date, but soon as you need client service from their side it takes forever. I requested paid up letters from this institute for my accounts that was paid and always there is a delay. And best of all is that when you follow up after 5 days they tell you again it will take another 5 days and then they will require prior proof of payments. YOU never asked for PoP before and the transfer is done from my FNB account to yours that is on my FNB profile so how must Iget a PoP for internal transfer from FNB to FNB. This is just lazy client service and nothing else
