Qwiekfin is a big ****. Preying on the vulnerable

I app**** online for a loan and came across qwiekfin. I received 2 debichecks and 1 was from them. I accidently accepted their debicheck and informed them immediately. I was told ithat R250 was for admin and another amount was for membership I asked them to cancel but they told me I can only cancel the membership. I told Chris that I'm taking it to helopeter if they continue and he threatened me with legal steps if I do. They still deducting from my bank account.
