Internet *******

I unsubscribed to showmax over a month month back ,they keep trying to debit my account every night and this is declined now there's a minus 320 odd rands on my account. Dineo that's talking to me online is asking me for person info about my card to verify my account? why when you trying to get money from that card every night? She says I have two active accounts how when I unsubscribed? You guys are internet ******* I want my bank charges paid ASAP and stop trying to access my account like its yours!!!!!!!!!!
