Terrible service

Hi... I had the most terrible experience with fnb as they called me on the 02/10/2017 for a new sim card with data that suppose to be cheaper The consultant advised me that i would receive my sim card as that is what she was selling to me, I advised her i am interested as the sale was good stating i would receive data and will be charged at on the 01/11/2017 I then received my card on the 04/10/2017 which gave me issues from the get go No data terrible service unable to use my internet etc I had to ask someone else to buy me data and pay him as i didnt have funds in my account aswell as what was stated in my call with the consultant I tried calling fnb for assistance where as the lady advised me i can only start using my sim card from the 01/11/2017 I feel that what was stated and what i got was terrible that they even charged me for everything on my account until today I am really sad to say that fnb is terrible
