I am so disappointed and frustrated

I received my checque account from FNB via a courier as I opened it teleohonically. I tried activating it on the online banking platform with no luck. I informed them, they have been transferring me from pillar to post and no one seem to understand my query. One told me that because I have a business account with them it might be that I am struggling to login because of that profile, but now what is the solution? I have been transferred many times and its Frustrating. I just want it cancelled because I am avoiding visiting a branch.
