FNB PATHETIC SERVICE

I opened a business account with FNB January 2020 after a back and forth battle and communication we finally got out paper work to continue business registration. I was sent a bank card with pin as well But i cannot access the online banking because i am told im not a customer. I downloaded app call in to call centre and told IS will call but nothing. I make transfer every month into ny business bank account but can't see or gave access online. The service from FNB has been pathetic nobody calls back to assist and the menu when calling i cant select a number it wknt allow, i then end up by wrong agent who says they will transfer and call cuts. All my accounts is by STD bank and i thought letd give FNB a chance with my business account BIG MISTAKE
