They ***** and will never give back

So I had this FNB connect SIM card deal with FNB last month I’ve canceled it and to my surprise this month I was debited once again. At this point I don’t know what I’m paying for if I don’t have airtime nor minutes nor data so really, what am I paying for? I called in to ask them this. The consultant said that she would put it to the admin team and they will have the cash reversed. I’m still waiting on a call but once again if you need something to be done from FNB they will take their time. But when FNB needs you they will go till the last. I hope this matter gets sorted as well as people are aware of their cons.
