FNB connect is a nightmare!!!

Saying 'yes' to the rep who phoned me and asked if I wanted an FNB connect contracts is one of the biggest mistakes I've ever made, it just won't end. First the rep blatantly **** to me, saying that whatsapp would be free (this turned out to be a month-long promotion), and that the total for my 2 sim cards with different supposed benefits would come to around R180. One was a top-up contract and the other would have 2 gigs of data per month and cannot be topped up. So imagine my surprise when I suddenly found R500-R600+ missing from my account. After a while I was too afraid to deposit any money into my account because FNB would just take everything immediately. This without me ever signing ANYTHING to authorise any of this. After spending hours on the phone the contracts were cancelled and one sim was made a prepaid, while the sim that had only data was now completely useless because it still cannot be topped up. In any case I was fed up with the whole thing so I went back to my vodacom sim and the fnb sims were in a drawer. I also found that I somehow owed R26000 on my fnb connect, on a top-up contract??? I couldn't even finish the data I had on the contracts and I barely phone anyone. Now, after a year of no drama, I start getting texts that no payment has been received for my fnb connect contracts. I went to the bank, all they could do was check if I had any contracts linked to my account and there was NO CONTRACTS. Then you phone the helpline and they tell you to go to the bank, when you go to the bank they say that you don't have an fnb connect contract. Once again I'm afraid to use my fnb account because my funds may start disappearing again. I also checked if there was any airtime or data loaded on the sim cards, since they're asking me to pay for it. The data sim has no data loaded, the top up contract shows 200mb data, 200minutes call time and 200 SMS's, but if I try to go online or make a call it says that I don't have any data, airtime or minutes. So no-one can help me, they don't keep records of dates on which the contract started, when they were made prepaid, no-one knows what's going on. If it will help I will take those sim cards to the bank and give it to them, they can have them, I don't want them. And in the meantime can't use my account. FNB clearly does not care about their customers, it's like they WANT me to close my account with them, I'm getting rude calls from debt collectors and Whatsapps (like we're in kindergarten) that I must urgently call some guy in connection with my nonexistent contracts. It's looking more ***** by the minute, I don't know what to do anymore.
