FNB SIM CARD DATA NEVER WORKS & NO FREE DATA AS PROMISED BY TELLER

I have an FNB SIM card and want to port back to Vodacom because the data never works when I am out. ALSO, I was told I would get free data every month which is UNTRUE. I asked the assistant twice if I would get free monthly data and she said YES, I would. I was left stranded at a hospital recently with a very sick husband and unable to call an Uber because my FNB data would not work. This was extremely stressful and I had to call a relative to order one for us.

I went to Vodacom for the fourth time to try and get ported back to them and when the assistant typed in the PIN she got a message saying FNB refused to port me back to Vodacom.

This is so stressful. I do not drive and I have wasted so much time trying to get my number ported back to Vodacom. I tried calling the bank and was told I must go into my bank. I CANNOT GET THERE AS I CANNOT GET BACK AS I CANNOT ORDER AN UBER AS THE DATA DOES NOT KICK IN. I am so angry and upset I am considering moving my bank account elsewhere over this terrible service. Why must I go into the bank to resolve this at my expense when it is something that can be resolved by FNB simply porting my number back to me?? Vodacom told me they have had lots of other unhappy customers using the FNB SIM card that want to port back.
