Very unprofessional and extremely rude

I walked to FNB on Sunday and dealt with a Hulisani to open 2 accounts. Your systems were off line and he offered to open the accounts and call the next day which he did but unfortunately the documentation he sent me which reads "customer information and agreement"for both accounts has the incorrect postal address and work telephone number. I have tried sending back the mail but it does not go through. I have called FNB 6 times either I have been cut off, directed to the wrong department told I cannot be assisted. The last call to ********** 404 was answered by a very rude and abrupt lady who told me she does not know what agreement I am talking about was constantly cut in while I was talking and transferred while I was trying to explain if this is the level of service I am to expect from FNB maybe I should consider using a different bank
