Fnb connect

In August I went to FEB to fetch my debit card, whIle we waited in Que a lady came and gave us free SIM prepaid cellphone cards. In Dec got a call an agent selling Fnb contracts which was meant to be active as from Jan, to me it was explained like I will receive airtime in Jan then they will debit end of the month. It was also explained that it is subject to approval. Beginning of Jan and mid Jan I checked there was no credits on the card then I thought it was not approved since there was no communication from then since the call. Took another option with another service provider suddenly now in Feb they sent an e-mail confirming debit I responded that I no longer require that service since I opted for another option. They contacted me and said I will pay the cancellation fee but I don't have that amount and requests the credits on the card to be reversed as I will use it as prepaid. However they went ahead and debited my bank account. I want the amount debited to be reversed as well as the credit on the SIM card and I will not afford to pay the cancellation fee. The agent gave me a stupid explanation that the they did not credit the card in Jan because de was no debit made
