Horrible service

I called FNB call centre to obtain my new account number as I'm unable to use the app because my phone is dead,I spoke to a consultant with the name Zandile Hlatswayo,she is very rude I do not like the way she spoke to me and I'm even planning to cancel my new account with FNB as I'm not ready to deal with such a horrible service,no one is willing to assist me so i will rather use a bank that will deal with clients professionally.
