I still can't use my FNB account

I had to lodge a Hellopeter complaint to get FNB to assist me previously. They called me within 48 hours, it meant another trip to the branch and another 2 and a half hours of queuing but was assured when we left there all is sorted. This was in the beginning of October. Its 5 weeks later and my daughter's account still doesn't work. We don't have the account number, the cellphone backing refuses her pin number, we tried registering for online banking but it keeps saying No data returned from request, we tried creating through the app but it just says to try again later. Today we tried via the ATM but is just says Cannot be processed try another ATM. It can't be this difficult to open up an account. Can someone please assist me.
