Impatient Consultant1

I am even ashamed that I decided to open an account with FNB, their sim card department have one of the most impatient staff when dealing with queries. Last week a consultant called Lerato was so impatient with me when I kept asking question through back and forth emails, she/he ended up referring me to the branch since she/he wanted to badly to dismiss me when I expressed my frustration about not understanding why was I billed for the sim card of data that I was not using. Furthermore when I opened the account I was told that the sim card was to make calls for enquiry and it was for free cause I never asked the bank to activate it for data usage. The last correspondence this consultant didn't even bother to respond to me. FNB has lost my trust and I have requested my account to be deactivated but still nobody bothered to assist me in this regard. I wish people could switch from FNB!
