fnb connect unlimited calling not unlimited

FNB :-) Alert! You have less than 10 MIN left on ********** 7448. To recharge your Voice bundle, logon to the FNB APP or fnb.co.za or dial *130*321#. T/Cs apply.

So I received this message today Very unfair as the the fair usage policy not explained to me I would like a copy of the recording when this package was sold to me.

I was also told that they use the Vodacom network. This was a lie as I keep getting cut of and one call becomes 100 calls. I use it to phone friends and family and now I receive messages like the following.

FNB :-) We detected high call usage on your Unlimited package. Please note this SIM may not be used for Business purposes, as per fair usage policy. T/Cs apply

I am not using it for this purpose and even if I was why does fnb sell unlimited packages to people when it clearly is limited. I want to cancel this contract I will take up one with Vodacom as their network actually works. I was sold a lie I am also strongly considering moving my accounts to another bank aswell. Fnb can't be trusted. I found the fair usage policy via Google after realizing I am being ****med
