I'm really angry at FNB services today THE 31Sst January 2019 I processed my daughter registration fees and added my email address to get POP (proof of payment) so I can send it to school as my daughter was on her way to register there,Beleived me sthis payment was done early morning at 8h45 its 10:42 I have not recieved the POP I call FNB to enquire about the Proof Of Payment as my dauughter is at the school and they cant help her without the POP this FNB lady I got on the phone "AFTER SHE SAID HOLD ON FOR 16MIN"tells me there nothing she can do due to their system not sending POP's and they are receiving calls of complains and they cant assist then I ask what other option can she do since I explain the situation we facing of my daughter being on school and no POP to process her registration "SHE SAID HOLD ON YET AGAIN" till the phone went off holding Honestly FNB WTH!!!!!!
