Changing banking limit is a nighmtare with FNB !!!

I have been trying to change my bank limit with FNB for some time now , I did it online , tried calling the bank, tried doing via the app and cellphone banking and yet it is a hassle .

The straw that broke the camel's back for me was when i was sent from department to department and nobody had a solution for me and then finally when i got a guy (Nduduzo) who could assist me he told me some story of how the system is blank and when i asked him how do I then get assisted he hung up on me

FNB this is shocking a simple request has left a sour taste in my mouth and why is it so difficult to get an answer and get sent from one department to another !!

Also I asked a rep to call me in 15 minutes time to close my credit card and yet there has ben ZERO action guys i want the credit card closed as it is now paid up as per the settlement amount given to me

FNB this is appalling and shocking !!!
