FNB IS REALLY MESSING WITH ME NOW!!!!!

So i opened a 32 days Flexi notice account with FNB last week Wednesday. When the lady sent me the confirmation documents i noticed that my street address was incorrect. I then called called FNB to get this matter resolved ASAP as i needed my bank statements to reflect the correct street address and i was told that it has been fixed which it was not. I then call again today and the call was answered by Poppy and she bluntly said that there is nothing that she can do as i will have to wait for a month for this to be resolved. This is the second time FNB is giving me this kind of service and i am now at a place were i really despise the level of service provide to me and the inconsiderate responses you give to me.

I cannot submit my documents now in which i was given a 7 day deadline which ends tomorrow and now i am being told that i cannot get this fixed immediately. I did not approve for FNB to change my address and how does it come about that i have to be inconvenienced by and forfeit everything whilst you guys continue acting as if everything is normal!!
