Money theft

I paid my account in full. The next moment I received an account for R35.00. Since I paid it in full I am not supposed to get anymore accounts till I make another purchase. The next moment I got an SMS stating I owe them R73.01. I did not buy anything but got this SMS. I got the account stating the reasons for the money I owe. In the account it states an SMS fee, some Men's Only thing I do not know about and interest of 70c. All this totals R34.90 per month. This is **************** and then they call me, threatening me with legal action. They put things on ones account one never asked and then they expect one to pay for it. It is a bunch of ******S, nothing else. The account number is not even displayed on the account I got. I went to the branch on the 23rd of December 2015, cut the card, handed it to one of the ladies and told her that I do not want to hear from them again. Warn people not to open accounts with this company. They are the worst of the worst.
